Non-woven microwave absorbing material, also known as high-power non-flammable microwave absorbing material, is a kind of hollow microwave broadband absorber made of flame-retardant, carbon black-impregnated non-woven fabric as a base material. At present, it is mainly used in the testing equipment of microwave anechoic chamber and cover-up anechoic chamber. If it is incident vertically and obliquely, it has excellent broadband performance, good scattering and isolation attenuation performance, suitable for all parts of the dark room.
