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.
2/
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.
