Аннотация:

The electromagnetic shields in the form of two-layer structures, the surface layer of which was the composite material with filler based on powdered titanium dioxide, and the inner one was the composite material with filler based on iron oxide, have been developed. The electromagnetic radiation reflection and transmission characteristics of the developed shields have been studied in the frequency range 0.7-142.8 GHz depending on the content of their inner layers. It has been found that electromagnetic radiation reflection and transmission coefficient values in the frequency range 0.7-142.8 GHz of the developed shields are –4.0…–27.0 dB and –10.0…–40.0 dB respectively. It has been experimentally proved that by impregnating by the calcium chloride aqueous solution of the powdered material that is part of the inner layer of such shields, it is possible to reduce by 5.0...45.0 dB of their electromagnetic radiation transmission coefficient values in the frequency range 2.0...26.0 GHz
