摘要：

Frequency dependences of transmission and reflection coefficients, dielectric permeability of composite materials with the various content of carbon fillers (technical carbon, graphite) in polyurethane varnish in ranges of frequencies 26-40 GHz and 110-260 GHz are experimentally investigated. It was found that composite material 0.4 mm thick with 4-5 % graphite mass content has a transmission coefficient of less than minus 7 dB in the whole investigated range of frequencies and can be effectively used in devices of protection from electromagnetic radiation.
