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. Do you seek a hybrid absorber for EMC testing applications? Check out our electromagnetic absorber brochures with detailed specifications and performance graphs.

DMAS microwave absorber: sustainable, long lasting
A standout feature of the DMAS microwave absorber is its sustainability. They are incredibly durable, fire retardant and resistant to changes in humidity. Because these are features of next gen microwave absorption materials (instead of hazardous ones) our products are fully REACH & RoHS compliant. Adding to their sustainable nature is the modular design. Accidentally damaged a pyramid? Just replace the broken one instead of the entire unit.
Our microwave absorbing materials do not leak carbon particles during their product life-cycle, meaning your laboratory remains a clean working environment. For more information you can check out our blog post comparing EPS vs foam material. If you want the most sustainable option, choose a DMAS microwave absorber.

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.
