Microwave absorber overview

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 it’s closed cell material structure (EPS) their performance is very stable over time. This leads to high quality and reproducible testing environments. 

DMAS Microwave absorbers are high performance, broad band polystyrene absorbers with an operating frequency from 200 MHz to 50 GHz. Due to excellent performance at microwave frequencies our MT absorber series is a superb choice for various antenna testing applications in Compact ranges and Radar Cross Section (RCS). Check out our absorber brochures with detailed specifications and performance graphs.

Stable performance

200 MHz - 50 GHz range

REACH & RoHS compliant

No leakage of carbon particles

25 year warranty

Fire retardant effects


Environmentally friendly

DMAS: 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 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 products do not leak carbon particles during their product life-cycle, meaning your laboratory remains a clean working environment. If you want the most sustainable option, choose a DMAS microwave absorber.
