Abstract

Electromagnetic shielding has become one of the most studied topics recently. Electromagnetic wave shielding is very important to protect sensitive electronic devices from electromagnetic interference and to protect living beings, especially humans, from the harmfull effects of electromagnetic waves. Basically, there are three mechanisms in shielding: reflection, absorption and multiple reflections. Many materials based on these mechanisms have been developed in the literature. Generally in the literature; concrete, wood, plasterboard, graphite, graphite cement, steel fiber cement, EPS filled cement-based composite, ferrite powder, rubber ferrite, conductive polypropyl film, spinel ferrite, carbon black cement-based composite, metallic sawdust, foamed concrete containing BFS, ceramics materials such as composite, polymer, polymer composite, cement-based material, nickel, Ca-Si plate, chipboard, ladle furnace slag (LFS), blast furnace slag (BFS), brick, phosphor materials, brass, SS304 stainless steel fibers and nanoparticles has been studied. To measure the electromagnetic shielding effectiveness, Multi-Channel-Coupling, Vector network analyzer (VNA), waveguide model and Field generator-spectrum analyzer pair are used.

Elektromanyetik Dalga Kalkanlaması Üzerine Bir Derleme Çalışması

Abstract

Elektromanyetik kalkanlama son zamanlarda en çok çalışılan konulardan birisi haline gelmiştir. Hassas elektronik cihazların elektromanyetik girişimden korunması ve elektromanyetik dalgaların zararlı etkisinden canlıların bilhassa insanların kurtulması için elektromanyetik dalga kalkanlaması çok önemlidir. Temelde kalkanlamada yansıma, soğurma ve çoklu yansıma başta olmak üzere 3 mekanizma vardır. Literatürde bu mekanizmaları temel alan birçok malzeme geliştirilmiştir. Genellikle literatürde; beton, ahşap, alçı levha, grafit, grafit çimento, çelik fiber çimento, EPS dolgulu çimento esaslı kompozit, ferrit tozu, kauçuk ferrit, iletken polipropil film, spinel ferrit, karbon siyahı çimento esaslı kompozit, metalik talaş, BFS içeren köpüklü beton, seramik kompozit, polimer, polimer kompozit, çimento esaslı malzeme, nikel, Ca-Si levha, sunta, pota fırını cürufu (LFS), yüksek fırın cürufu (BFS), tuğla, fosfor malzemeleri, pirinç, SS304 paslanmaz çelikten lifler ve nanopartiküller gibi malzemeler çalışılmıştır. Elektromanyetik kalkanlama verimliliğini ölçmek için ise, Multi-Channel-Coupling, Vektör ağ analizörü (VNA), dalga kılavuzu modeli ve Field generator-spektrum analizör çifti kullanılmıştır.
