Film Fiber Radio-Absorbing Material

The dielectric properties of nonwoven webs and polymer films filled with dispersed carbon web, as well as multilayer materials obtained by addition of webs and films, were investigated. Webs and films have a pronounced interference mechanism of absorption of electromagnetic waves. Dielectric properties with an asymmetric structure relative to the middle of the thickness of the multilayer materials depend on the side on which electromagnetic radiation enters the material. Multilayer materials based on nonwoven web and polymer films have an interference absorption mechanism, but their use expands the frequency range of absorption of electromagnetic radiation.
