RF Absorbers for EMC testing & Antenna measurements
Unlike conventional foam absorbers, DMAS polystyrene absorbers are highly rigid and resistant to changes in humidity. In addition, our pyramidal absorbers do not leak any carbon particles, they comply with international fire retardancy standards and they come with a 25 year warranty. Superior, closed-cell technology certainly has its advantages.
DMAS offers two distinct product groups: hybrid absorbers and microwave absorbers. They each have their own performance characteristics and serve specific applications. When combined with ferrite tiles, our hybrid absorbers are perfect for EMC testing in semi and full anechoic chambers.
Microwave absorbers provide excellent performance for both near field measurements in antenna test ranges and wireless (OTA) test chambers. For easier access to antenna under test for engineers, we also offer high end walkway absorbers with reinforced fiberglass epoxy grid panels.
Specifically for MIL-STD461 test chambers we can offer a cost effective solution without the need for expensive ferrite tiles. In case you are interested, you can find more info about our MIL-STD absorbers here.

For a long time, you had to choose between performance and longevity when it came to absorbers. With DMAS polystyrene RF absorbers, that is no longer the case.
Thanks to next-gen material properties, our absorbers combine an astounding +25 year life span with full REACH & RoHS compliance. Since performance does not degrade over time, it is not an exaggeration to state that DMAS absorbers have no downsides.
