FIELD: electricity.
SUBSTANCE: invention can be used for providing electromagnetic compatibility of radioelectronic equipment, radio-frequency radiation protection and reducing radar signature of various objects. Present invention consists in that electromagnetic waves absorber based on hybrid nanocomposite structures consists of layers of nonwoven carbon-containing polymer material with low density, in which carbon concentration monotonously varies from layer to layer, non-woven carbon-containing polymer material used is carbonised polyacrylonitrile, layers of which are impregnated with a suspension containing nanoporous carbon microfibres and multilayer carbon nanoparticles of fulleroid type with a toroid shape, wherein layers of polyacrylonitrile are carbonised to carbon concentration of 1 wt% to 99.999 wt% with increase from surface to central layer.
EFFECT: possibility of improving absorbent properties.
