Microwave absorber overview

Microwave absorber made to attenuate RF/MW signals

Since the introduction of DMAS microwave absorbers back in 2011 our portfolio has evolved to the next level. With the introduction of the Javelin Tip (JT) absorbers DMAS made a crucial step towards excellent performance without compromising product features. Our absorbers have a superior product life-cycle of +25 years and due to the closed cell structure (EPS) of the microwave absorption material, their performance is very stable over time. This leads to high quality microwave absorbing material and reproducible testing environments.

DMAS RF absorbers are high performance, broadband polystyrene absorbers with an operating frequency from 200 MHz to 50 GHz. Due to excellent reflectivity at microwave frequencies our MT absorber series is a superb choice for various antenna testing applications in Compact ranges.

Easy EUT access

Walkway microwave absorbers

Are you looking for ways to provide easy access to equipment-under-test for your research engineers? DMAS microwave absorbers are also available as a walkway variant.

A fiberglass epoxy grid is a microwave absorbing material that provides great support. While clever design and optimal placement minimize unwanted interference. For more detailed information on our walkway absobers, visit the walkway product page.
