NONWOVEN MULTILAYER MATERIAL FOR ABSORPTION OF ELECTROMAGNETIC RADIATION IN THE MICROWAVE RANGE Russian patent published in 2018 - IPC D04H1/728 

FIELD: physics.

SUBSTANCE: invention relates to the field of radiophysics and is intended for absorbing electromagnetic radiation of the ultra-high frequency (microwave) range, and its structure and properties meet the requirements of creating elements of wearing clothes for masking people in the microwave range. Nonwoven material for absorbing electromagnetic radiation of the microwave range containing dielectric fibers, is characterized by carbonaceous elements with a size of 50 to 100 nm are built into the structure of dielectric fibers, made by the method of capillarless electrostatic molding from a solution of polymers based on polyacrylonitrile (PAN), with a diameter dielectric fibers do not exceed 500 nm. Invention provides the possibility of masking a person in the microwave range.

EFFECT: technical result consists in reducing the value of the surface density without reducing the attenuation coefficient.
