DEVICE MADE OF POLYMER COMPOSITE MATERIALS FOR REDUCING RADAR VISIBILITY OF DIFFERENT OBJECTS Russian patent published in 2016 - IPC H01Q17/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering. Device is a multilayer structure consisting of several layers: outer layer made from dielectric material, absorbing inner layers of electroconductive tissue connected by layers of dielectric substance, and a back layer. Outer layer is made from light fibre-glass, back layer is made of carbon fibre-reinforced plastic with high conductivity to prevent ingress of electromagnetic radiation inside room, and absorbent inner layers of electroconductive tissue have surface electrical resistance 100÷1,000 ohm. Outer layer is made of material with low relative permittivity of 1.7-2.5, providing soft electrodynamic input radio waves inside material and low coefficient of reflection from surface of device.

EFFECT: technical result is wider frequency range of absorbed radio radiation.
