Abstract

This paper presents the results of a study on radio-absorbing materials in the ultra-high frequency range of 78-118 GHz. Crystalline graphite powder (particle size 0.1 mm) was considered as the main radio-absorbing material. Epoxy resin was used as a substrate and a binder. The samples were prepared by dispersing the graphite powder across the surface of the epoxy resin substrate. The most effective working thickness of epoxy resin has been established experimentally. The geometric dimensions of the arrangement of the installation components at which the most effective signal recording is observed are calculated. The results of the studies showed that a film consisting of graphite particles on the surface of epoxy resin effectively shields radio emissions in the 3-millimeter range.
