A Review Study on Electromagnetic Wave Shielding

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.
