ELECTROMAGNETIC ABSORBING COAT Russian patent published in 2009 - IPC C09D5/32 B82B1/00 

FIELD: instrument making.

SUBSTANCE: invention relates to coats absorbing electromagnetic radiation. Proposed coat comprises a warp consisting of aramide high-modulus Kevlar-type fabric with absorbing film applied thereon. Various-type films are applied on every warp. One type represents sawed ferrite with nano-size clusters of Ni and Co ingrained thereto, while the second type is made from evaporated hydrogenated carbon with nano-size clusters of Ni and Co ingrained thereto. The films are evaporated onto aramide fabric on both sides. In designing the fabric structure, layers are taken to alternate so that the concentration of ferromagnetic clusters in films of adjacent layers varies from low (40 to 60% at.) to high (60 to 80% at.).

EFFECT: higher RF absorbing properties in 6 to 40 GHz range and expanded frequency range in lower SHF range band of 2 to 6 GHz.
