1/ Description 2/ Exceptional absorption characteristics AEMI offers Broadband Convoluted absorbers that are manufactured from lightweight urethane foam impregnated with a dielectric material. The front surface is rippled, providing a good match to the impinging wavefront. The convoluted design, when properly loaded, exhibits exceptional absorption characteristics in the millimeter range, especially at wide angles of incidence.
