(PANI) fibers was synthesized by in situ polymerization. FTIR, XRD, SEM, and vector network analyzer were used to investigate chemical composition, micro-morphology, electromagnetic properties and microwave absorbing properties of the composite. The results show that PANI fibers were grafted on the surfaces of LZFO particles. The reflection loss exceeds 10 dB in the frequency range from 2.5 to 5 GHz and from 15 to 17GHz, and the maximum reflection loss reaches -33 dB at 15.9GHz. The enhanced microwave absorption properties of LZFO/PANI-fiber composites are mainly ascribed to the combined effect of both dielectric loss and magnetic loss and the improved impedance matching. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li%E2%82%80.%E2%82%83%E2%82%85Zn%E2%82%80.%E2%82%83Fe%E2%82%82.%E2%82%83%E2%82%85O%E2%82%84" title="Li₀.₃₅Zn₀.₃Fe₂.₃₅O₄">Li₀.₃₅Zn₀.₃Fe₂.₃₅O₄</a>, <a href="https://publications.waset.org/abstracts/search?q=polyaniline" title=" polyaniline"> polyaniline</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20properties" title=" electromagnetic properties"> electromagnetic properties</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20absorbing%20properties" title=" microwave absorbing properties"> microwave absorbing properties</a> </p> <a href="https://publications.waset.org/abstracts/60781/synthesis-and-electromagnetic-property-of-li035zn03fe235o4-grafted-with-polyaniline-fibers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60781.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">430</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9405</span> Fabricating an Infrared-Radar Compatible Stealth Surface with Frequency Selective Surface and Structured Radar-Absorbing Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qingtao%20Yu">Qingtao Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Guojia%20Ma"> Guojia Ma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Approaches to microwave absorption and low infrared emissivity are often conflicting, as the low-emissivity layer, usually consisting of metals, increases the reflection of microwaves, especially in high frequency. In this study, an infrared-radar compatible stealth surface was fabricated by first depositing a layer of low-emissivity metal film on the surface of a layer of radar-absorbing material. Then, ultrafast laser was used to generate patterns on the metal film, forming a frequency selective surface. With proper pattern design, while the majority of the frequency selective surface is covered by the metal film, it has relatively little influence on the reflection of microwaves between 2 to 18 GHz. At last, structures on the radar-absorbing layer were fabricated by ultra-fast laser to further improve the absorbing bandwidth of the microwave. This study demonstrates that the compatibility between microwave absorption and low infrared emissivity can be achieved by properly designing patterns and structures on the metal film and the radar-absorbing layer accordingly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frequency%20selective%20surface" title="frequency selective surface">frequency selective surface</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared-radar%20compatible" title=" infrared-radar compatible"> infrared-radar compatible</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20infrared%20emissivity" title=" low infrared emissivity"> low infrared emissivity</a>, <a href="https://publications.waset.org/abstracts/search?q=radar-absorbing%20material" title=" radar-absorbing material"> radar-absorbing material</a>, <a href="https://publications.waset.org/abstracts/search?q=patterns" title=" patterns"> patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=structures" title=" structures"> structures</a> </p> <a href="https://publications.waset.org/abstracts/115550/fabricating-an-infrared-radar-compatible-stealth-surface-with-frequency-selective-surface-and-structured-radar-absorbing-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115550.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9404</span> MWCNT/CuFe10Al2O19/Polyanilie Nanocomposite for Microwave Absorbing Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pallab%20Bhattacharya">Pallab Bhattacharya</a>, <a href="https://publications.waset.org/abstracts/search?q=C.%20K.%20Das"> C.

The recent work is attentive to the preparation of nanocomposite based on acid modified MWCNT, hexagonal shaped magnetic M-type hexaferrite (CuFe10Al2O19) and polyaniline. CuFe10Al2O19 was prepared by a facile chemical co-precipitation method. An in-situ approach was employed for the coating of polyaniline on MWCNT/CuFe10Al2O19 nanocomposite. The final fabrication of this nanocomposite for microwave measurements was done suitably in the matrix of thermoplastic polyurethane with 10% filler content. The nanocomposites showed the maximum reflection loss of -60.2 dB (in X-band) at the thickness of 2.5 mm with a broad absorption range in contrast to the pristine MWCNT and CuFe10Al2O19. Addition of PANI improves the microwave absorption property of the nanocomposites. The thermal stability of the prepared nanocomposites is also very high. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20materials" title="magnetic materials">magnetic materials</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20absorption" title=" microwave absorption"> microwave absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=MWCNT" title=" MWCNT"> MWCNT</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposites" title=" nanocomposites"> nanocomposites</a> </p> <a href="https://publications.waset.org/abstracts/13923/mwcntcufe10al2o19polyanilie-nanocomposite-for-microwave-absorbing-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13923.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">299</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9403</span> Microwave-Assisted Eradication of Wool </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Salama">M.

We have to focus on the parameters of absorbing materials such as permittivity, permeability, and thickness so that best absorbing according to our necessity can happen. The real and imaginary parts of the relative complex permittivity (ε<sub>r</sub>' and ε<sub>r</sub>") and permeability (µ<sub>r</sub>' and µ<sub>r</sub>") were obtained by simulation. The microwave absorbing property of carbon and Ni(C) is simulated in this study by MATLAB software; the simulation was in the frequency range between 2 to 12 GHz for carbon black (C), and carbon coated nickel (Ni(C)) with different thicknesses. In fact, we draw reflection loss (RL) for C and Ni-C via frequency. We have compared their absorption for 3-mm thickness and predicted for other thicknesses by using of electromagnetic wave transmission theory. The results showed that reflection loss position changes in low frequency with increasing of thickness. We found out that, in all cases, using nanocomposites as absorbance cannot get better results relative to pure nanoparticles. The frequency where absorption is maximum can determine the best choice between nanocomposites and pure nanoparticles. Also, we could find an optimal thickness for long wavelength absorbing in order to utilize them in protecting shields and covering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorbing" title="absorbing">absorbing</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon" title=" carbon"> carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nickel" title=" carbon nickel"> carbon nickel</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency" title=" frequency"> frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=thicknesses" title=" thicknesses"> thicknesses</a> </p> <a href="https://publications.waset.org/abstracts/80056/simulation-of-reflection-loss-for-carbon-and-nickel-carbon-thin-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80056.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">186</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9400</span> Overview of the Various Factors Affecting the Properties of Microwave and Millimeterwave Dielectric Ceramics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Manan">Abdul Manan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dielectric Resonators (DRs) have revolutionized the microwave wireless communication industry globally. There are three directions for research in ceramics for application in telecommunication industry Three key properties of ceramic dielectrics that determine their functionality at microwave and millimetrewave frequencies include relative permittivity (εr), unloaded quality factor Qu- the inverse of the dielectric loss (tanδ) and temperature coefficient of resonant frequency (τf). Each direction requires specific properties. These dielectric properties are affected by a number of factors. These includes tolerance factor, onset of structural phase transitions, dark core formation, processing conditions, raw materials and impurities, order/disorder behavior, compositional ordering, porosity, humidity, grain size, orientation of the crystallites, and grain boundaries. The data related to these factors is scattered. The main purpose of this review is to bring these together and present the effects of these factors on the microwave dielectric properties. Control of these factors is important for improvement in the microwave properties.

This harmful radiation creates not only malfunctioning of nearby electronic gadgets but also severely affects a human being. So, a suitable microwave absorbing material (MAM) becomes a necessary urge in the field of stealth and radar technology. Initially, Aluminum based hexa ferrite was prepared by sol-gel technique and for carbon derived composite was prepared by the simple one port chemical reduction method. Finally, composite films of Poly (Vinylidene) Fluoride (PVDF) are prepared by simple gel casting technique. Present work demands that aluminum-based hexaferrite phase conjugated with graphene in PVDF matrix becomes a suitable candidate both in commercially important X and Ku band. The structural and morphological nature was characterized by X-Ray diffraction (XRD), Field emission-scanning electron microscope (FESEM) and Raman spectra which conforms that 30-40 nm particles are well decorated over graphene sheet. Magnetic force microscopy (MFM) and conducting force microscopy (CFM) study further conforms the magnetic and conducting nature of composite. Finally, shielding effectiveness (SE) of the composite film was studied by using Vector network analyzer (VNA) both in X band and Ku band frequency range and found to be more than 30 dB and 40 dB, respectively. As prepared composite films are excellent microwave absorbers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanocomposite" title="carbon nanocomposite">carbon nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20absorbing%20material" title=" microwave absorbing material"> microwave absorbing material</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20shielding" title=" electromagnetic shielding"> electromagnetic shielding</a>, <a href="https://publications.waset.org/abstracts/search?q=hexaferrite" title=" hexaferrite"> hexaferrite</a> </p> <a href="https://publications.waset.org/abstracts/92209/aluminum-based-hexaferrite-and-reduced-graphene-oxide-a-suitable-microwave-absorber-for-microwave-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92209.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">178</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9398</span> Acoustic Performance and Application of Three Personalized Sound-Absorbing Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fangying%20Wang">Fangying Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Sanming"> Zhang Sanming</a>, <a href="https://publications.waset.org/abstracts/search?q=Ni%20Qian"> Ni Qian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, more and more personalized sound absorbing materials have entered the Chinese room acoustical decoration market.

A number of processing techniques have been developed to obtain high quality carbide tools, with a wide range of grain size depending on the application and requirements. Microwave sintering is one of the heating processes, which has been used on a wide range of materials including ceramics. The complete understanding of microwave sintering and its contribution towards control of grain growth and on deformation of the resulting carbide materials needs further studies and attention. In addition, the effect of binder materials and their behaviour as a function of microwave sintering is another area that requires clear understanding. This review aims to focus on microwave sintering, providing information of how the process works and what type of materials it is best suited for. In addition, a closer look at some microwave sintered Tungsten Carbide-Cobalt samples will be taken and discussed, addressing some of the key issues and challenges faced in the research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cemented%20carbides" title="cemented carbides">cemented carbides</a>, <a href="https://publications.waset.org/abstracts/search?q=consolidation" title=" consolidation"> consolidation</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20sintering" title=" microwave sintering"> microwave sintering</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties "> mechanical properties </a> </p> <a href="https://publications.waset.org/abstracts/32637/microwave-sintering-and-its-application-on-cemented-carbides" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32637.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">596</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9396</span> Dielectric Properties of La2MoO6 Ceramics at Microwave Frequency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yih-Chien%20Chen">Yih-Chien Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Cheng%20You"> Yu-Cheng You</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The microwave dielectric properties of La2MoO6 ceramics were investigated with a view to their application in mobile communication.

This study was performed to gain a better understanding of the wave-absorbing phenomenon of magnetic RAMs. First, we hypothesized that the absorbing phenomenon is dependent on the particle shape. Using the Material Studio program and the micro-dot magnetic dipoles (MDMD) method, we obtained results from magnetic RAMs to support this hypothesis. The total MDMD energy of disk-like iron particles was greater than that of spherical iron particles. In addition, the particulate aggregation phenomenon decreases the wave-absorbance, according to both experiments and computational data. To conclude, this study may be of importance in terms of explaining the wave- absorbing characteristic of magnetic RAMs. Combining molecular dynamics simulation results and the theory of magnetization of magnetic dots, we investigated the magnetic properties of iron materials with different particle shapes and degrees of aggregation under external magnetic fields. The MDMD of the materials under magnetic fields of various strengths were simulated. Our results suggested that disk-like iron particles had a better magnetization than spherical iron particles. This result could be correlated with the magnetic wave- absorbing property of iron material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wave-absorbing%20property" title="wave-absorbing property">wave-absorbing property</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20material" title=" magnetic material"> magnetic material</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-dot%20magnetic%20dipole" title=" micro-dot magnetic dipole"> micro-dot magnetic dipole</a>, <a href="https://publications.waset.org/abstracts/search?q=particulate%20aggregation" title=" particulate aggregation"> particulate aggregation</a> </p> <a href="https://publications.waset.org/abstracts/78242/computer-simulation-to-investigate-magnetic-and-wave-absorbing-properties-of-iron-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78242.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">490</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9394</span> Recent Development on Application of Microwave Energy on Process Metallurgy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mamdouh%20Omran">Mamdouh Omran</a>, <a href="https://publications.waset.org/abstracts/search?q=Timo%20Fabritius"> Timo Fabritius</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A growing interest in microwave heating has emerged recently. Many researchers have begun to pay attention to microwave energy as an alternative technique for processing various primary and secondary raw materials. Compared to conventional methods, microwave processing offers several advantages, such as selective heating, rapid heating, and volumetric heating. The present study gives a summary on our recent works related to the use of microwave energy for the recovery of valuable metals from primary and secondary raw materials. The research is mainly focusing on: Application of microwave for the recovery and recycling of metals from different metallurgical industries wastes (i.e. electric arc furnace (EAF) dust, blast furnace (BF), basic oxygen furnace (BOF) sludge). Application of microwave for upgrading and recovery of valuable metals from primary raw materials (i.e. iron ore). The results indicated that microwave heating is a promising and effective technique for processing primary and secondary steelmaking wastes. After microwave treatment of iron ore for 60 s and 900 W, about a 28.30% increase in grindability.Wet high intensity magnetic separation (WHIMS) indicated that the magnetic separation increased from 34% to 98% after microwave treatment for 90 s and 900 W. In the case of EAF dust, after microwave processing at 1100 W for 20 min, Zinc removal from 64 % to ~ 97 %, depending on mixture ratio and treatment time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dielectric%20properties" title="dielectric properties">dielectric properties</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20heating" title=" microwave heating"> microwave heating</a>, <a href="https://publications.waset.org/abstracts/search?q=raw%20materials" title=" raw materials"> raw materials</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20raw%20materials" title=" secondary raw materials"> secondary raw materials</a> </p> <a href="https://publications.waset.org/abstracts/156829/recent-development-on-application-of-microwave-energy-on-process-metallurgy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156829.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">95</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9393</span> Effect of Ba Addition on the Dielectric Properties and Microstructure of (Ca₀.₆Sr₀.₄)ZrO₃</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ying-Chieh%20Lee">Ying-Chieh Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Huei-Jyun%20Shih"> Huei-Jyun Shih</a>, <a href="https://publications.waset.org/abstracts/search?q=Ting-Yang%20Wang"> Ting-Yang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Pithan"> Christian Pithan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focuses on the synthesis and characterization of Ca₀.₆Sr₀.₄₋ₓBaₓZrO₃ (x = 0.01, 0.04, 0.07, and 0.10) ceramics prepared via the solid-state method and sintered at 1450 °C.

If the method is used instead of experimental tuning in the development of car interior material, the time and money can be saved, and then, the development effort can be reduced because it can be optimized by simulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-layer%20nonwoven" title="multi-layer nonwoven">multi-layer nonwoven</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20absorption%20coefficient" title=" sound absorption coefficient"> sound absorption coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=scaled%20reverberation%20chamber" title=" scaled reverberation chamber"> scaled reverberation chamber</a>, <a href="https://publications.waset.org/abstracts/search?q=impedance%20tubes" title=" impedance tubes"> impedance tubes</a> </p> <a href="https://publications.waset.org/abstracts/60069/the-prediction-of-sound-absorbing-coefficient-for-multi-layer-non-woven" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60069.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">376</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9387</span> Microwave Sanitization of Polyester Fabrics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Haggag">K.

In the present work the nanocrystalline CaZrTi2O7 was synthesized from Calcium Zirconyl Titanate tartrate precursor (CZTT) employing two different heating techniques such as Conventional heating (Muffle furnace) and Microwave heating (Microwave Oven). Thermal decomposition of the CZTT precursors in air yielded nanocrystalline CaZrTi2O7 powder as the end product. The products obtained by annealing the CZTT precursor using both heating method were characterized using simultaneous TG-DTA, FTIR, XRD, SEM, TEM, NTA and thermodilatometric study. The physical characteristics such as crystallinity, morphology and particle size of the product obtained by heating the CZTT precursor at the different temperatures in a Muffle furnace and Microwave oven were found to be significantly different. The microwave heating technique considerably lowered the synthesis temperature of CaZrTi2O7. The influence of microwave heating was more pronounced as compared to Muffle furnace heating.

The present research work discusses the design of composites that are suitable to minimize EMI through various stacking sequences. The carbon fibers reinforced composite structures impregnated with dielectric (MWCNTs) and magnetic nanofillers (Fe₂O₃) were developed to investigate their microwave absorption properties. The composite structure comprising a single type of nanofillers, each of MWCNTs & Fe₂O₃, was developed, and then their layers were stacked over each other with various stacking sequences to investigate the best stacking sequence, which presents good microwave absorption characteristics. A vector network analyzer (VNA) was used to analyze the microwave absorption properties of these developed composite structures. The composite structures impregnated with the layers of a dielectric nanofiller and sandwiched between the layers of a magnetic nanofiller show the highest EMI shielding value of 59 dB and a dielectric conductivity of 35 S/cm in the frequency range of 0.1 to 13.6 GHz. The results also demonstrate that the microwave absorption properties of the developed composite structures were dominant over reflection properties. The absence of an external peak in X-ray diffraction (XRD), marked the purity of the added nanofillers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanocomposites" title="nanocomposites">nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20absorption" title=" microwave absorption"> microwave absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=EMI%20shielding" title=" EMI shielding"> EMI shielding</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20depth" title=" skin depth"> skin depth</a>, <a href="https://publications.waset.org/abstracts/search?q=reflection%20loss" title=" reflection loss"> reflection loss</a> </p> <a href="https://publications.waset.org/abstracts/183146/effect-of-laminating-sequence-of-mwcnts-and-fe2o3-filled-nanocomposites-on-emi-shielding-effectiveness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183146.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">52</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9384</span> Electrostatic and Dielectric Measurements for Hair Building Fibers from DC to Microwave Frequencies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Y.%20You">K.

This study focused on upgrading the waste teakwood through microwave torrefaction processes and investigating the key operating parameters to improve energy density for the quality of biochar production. The experiments were carried out in a 250 mL reactor placed in a microwave cavity on two different media, inert and non-inert. The microwave was operated at a frequency of 2.45GHz with power level variations of 540W, 720W, and 900W, respectively. During torrefaction processes, the nitrogen gas flows into the reactor at a rate of 0.125 mL/min, and the air flows naturally. The temperature inside the reactor was observed every 0.5 minutes for 20 minutes using a K-Type thermocouple. Changes in the mass and the properties of the torrefied products were analyzed to predict the correlation between calorific value, mass yield, and level power of the microwave. The results showed that with the increase in the operating power of microwave torrefaction, the calorific value and energy density of the product increased significantly, while mass and energy yield tended to decrease. Air can be a great potential media for substituting the expensive nitrogen to perform the microwave torrefaction for teakwood biomass. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=torrefaction" title="torrefaction">torrefaction</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20heating" title=" microwave heating"> microwave heating</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20enhancement" title=" energy enhancement"> energy enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20and%20energy%20yield" title=" mass and energy yield"> mass and energy yield</a> </p> <a href="https://publications.waset.org/abstracts/161314/microwave-assisted-torrefaction-of-teakwood-biomass-residues-the-effect-of-power-level-and-fluid-flows" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161314.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9380</span> Characteristics of Aerosols Properties Over Different Desert-Influenced Aeronet Sites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abou%20Bakr%20Merdji">Abou Bakr Merdji</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Mhawish"> Alaa Mhawish</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaofeng%20Xu"> Xiaofeng Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chunsong%20Lu"> Chunsong Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The characteristics of optical and microphysical properties of aerosols near deserts are analyzed using 11 AErosol RObotic NETwork (AERONET) sites located in 6 major desert areas (the Sahara, Arabia, Thar, Karakum, Taklamakan, and Gobi) between 1998 and 2021. The regional mean of Aerosol Optical Depth (AOD) (coarse AOD (CAOD)) are 0.44 (0.187), 0.38 (0.26), 0.35 (0.24), 0.23 (0.11), 0.20 (0.14), 0.10 (0.05) in the Thar, Arabian, Sahara, Karakum, Taklamakan and Gobi Deserts respectively, while an opposite for AE and Fine Mode Fraction (FMF). Higher extinctions are associated with larger particles (dust) over all the main desert regions. This is shown by the almost inversely proportional variations of AOD and CAOD compared with AE and FMF. Coarse particles contribute the most to the total AOD over the Sahara Desert compared to those in the other deserts all year round. Related to the seasonality of dust events, the maximum AOD (CAOD) generally appears in summer and spring, while the minimum is in winter. The mean values of absorbing AOD (AAOD), Absorbing AE (AAE), and the Single Scattering Albedo (SSA) for all sites ranged from 0.017 to 0.037, from 1.16 to 2.81 and from 0.844 to 0.944, respectively. Generally, the highest absorbing aerosol load are observed over the Thar, followed by the Karakum, the Sahara, the Gobi, and then the Taklamakan Deserts, while the largest absorbing particles are observed in the Sahara followed by Arabia, Thar, Karakum, Gobi, and the smallest over the Taklamakan Desert. Similar absorption qualities are observed over the Sahara, Arabia, Thar, and Karakum Deserts, with SSA values varying between 0.90 and 0.91, whereas the most and least absorbing particles are observed at the Taklamakan and the Gobi Deserts, respectively. The seasonal AAODs are distinctly different over the deserts, with parts of Sahara and Arabia, and the Dalanzadgad sites experiencing the maximum in summer, the Southern Sahara, Western Arabia, Jaipur, and Dushanbe in winter, while the Eastern Arabia and the Muztagh Ata in autumn. AAOD and SSA spectra are consistent with dust-dominated conditions that resulted from aerosol typing (dust and polluted dust) at most deserts, with a possible presence of other absorbing particles apart from dust at Arabia, the Taklamakan, and the Gobi Desert sites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sahara" title="sahara">sahara</a>, <a href="https://publications.waset.org/abstracts/search?q=AERONET" title=" AERONET"> AERONET</a>, <a href="https://publications.waset.org/abstracts/search?q=desert" title=" desert"> desert</a>, <a href="https://publications.waset.org/abstracts/search?q=dust%20belt" title=" dust belt"> dust belt</a>, <a href="https://publications.waset.org/abstracts/search?q=aerosols" title=" aerosols"> aerosols</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20properties" title=" optical properties"> optical properties</a> </p> <a href="https://publications.waset.org/abstracts/166795/characteristics-of-aerosols-properties-over-different-desert-influenced-aeronet-sites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166795.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9379</span> Structural and Electromagnetic Properties of CoFe2O4-ZrO2 Nanocomosites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ravinder%20Reddy%20Butreddy">Ravinder Reddy Butreddy</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadhana%20Katlakunta"> Sadhana Katlakunta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The nanocomposites of CoFe2O4-xZrO2 with different loadings of ZrO2 (x = 0.025, 0.05, 0.075, 0.1 and 1.5) were prepared using ball mill method.

The material used is sugarcane bagasse (SCB) which is one of the new materials that used to fabricate the microwave absorber. The complex permittivity was measured using Agilent dielectric probe technique. The designs were simulated using CST Microwave Studio Software.

The preparation process involves several steps, including drying, which affects the structure and quality of the vermicelli. This study aims to examine the effects of different drying technologies on the rehydration time and quality of mung bean vermicelli. Three drying technologies, namely hot air drying, microwave continuous drying, and microwave vacuum drying, were used for the drying process. The vermicelli strands were dried at 45°C for 12h in a hot air dryer, at 70 Hz of conveyor belt speed inverter in a microwave continuous dryer, and at 30 W.g⁻¹ of microwave power density in a microwave vacuum dryer. The results showed that mung bean vermicelli dried using hot air drying had the longest rehydration time of 12.69 minutes. On the other hand, vermicelli dried through microwave continuous drying and microwave vacuum drying had shorter rehydration times of 2.79 minutes and 2.14 minutes, respectively. Microwave vacuum drying also resulted in larger porosity, higher water absorption, and cooking loss. The tensile strength and elasticity of vermicelli dried using hot air drying were higher compared to microwave drying technologies. The sensory evaluation did not reveal significant differences in most attributes among the vermicelli treatments. Overall, microwave drying technology proved to be effective in reducing rehydration time and producing good-quality mung bean vermicelli. <p class="card-text"><strong>Keywords:</strong> <a
