Owner's manual

1/ 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.
