Description

AEMI offers Broadband Convoluted absorbers that are
manufactured from lightweight urethane foam impregna-
ted with a dielectric material.
The front surface is rippled, providing a good match to the
impinging wavefront.

Exceptional absorption characteristics

The convoluted design, when properly loaded, exhibits
exceptional absorption characteristics in the millimeter
range, especially at wide angles of incidence. The convo-
luted material has properties desirable for applications
requiring high refl ectivity performance in conjunction with
low forward scattering characteristics.
