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.
A DMAS absorber is a truly high quality product. Our cutting-edge hybrid and microwave absorbers are designed and manufactured in The Netherlands, fully in line with European Health, Environment and Safety regulations.
With the biggest European port (Rotterdam) close to hand, container shipment to anywhere on the globe is a trivial matter. Strict ISO 9001 and ISO 14001 standards apply to each step of production and samples are tested frequently to ensure benchmark levels of quality and performance.
But that’s not all. DMAS has close affiliations with local partners that supply tailored semi anechoic chambers and antenna testing solutions. We fully understand the needs of our clients when it comes to dependability, performance and expert advice. Our extensive experience in the field of absorber technology is leveraged to offer just that.

This 5-inch (13cm) absorber is specifically designed for smaller wireless antenna test setups, like OTA boxes or cabinets. The operating frequency is 2GHz up to 110GHz.
With a total height of 12-inch (30cm) this microwave absorber’ reflectivity performance is outstanding. Among other USP’s, DMAS absorbers are made of expanded polystyrene (EPS) and come with great benefits over traditional foams.
Introducing the MT45-JT (18”) absorber: a long-lasting, javelin-tipped, polystyrene absorber. Among other USP’s, DMAS absorbers are humidity resistant and made of closed-cell material. This provides great benefits over traditional foam materials, such as no leakage of carbon particles.
This polystyrene absorber offers the enormous benefit of meeting reflectivity requirements part of MIL-STD461 guidelines, even when no ferrite tile base is utilized. This means a great cost reduction can be achieved using the MT50 absorber.
The tallest DMAS absorber is the MT65-JT. This 26-inch absorber is designed for measurements at very low frequencies. Its operating frequency starts at 200MHz. Among other USP’s, DMAS absorbers are lightweight and easy to install. (Adhesive-free installations)
The HT25 absorber is typically used in CISPR25 or MIL-STD461 (EMC) test chambers. Perfectly tuned for use in semi anechoic chambers, DMAS Hybrid EMC Absorbers are all specifically matched for use in combination with compatible ferrite tiles.
DMAS Hybrid Absorber models are broadband, closed-cell carbon loaded polystyrene absorbers and are specifically tuned for perfect performance in semi- and full anechoic chambers using a matching ferrite tile.
DMAS Hybrid Absorbers are carbon loaded polystyrene absorbers and are specifically tuned for perfect performance in semi- and full anechoic chambers. The fact polystyrene is a closed-cell material provides great advantages over traditional polyfoam alternatives.
Need quick access to your antenna or Device Under Test (DUT)? Tired of getting first the floor absorbers out of the way before you can make adjustments in your setup? With DMAS walkway absorbers you have an immediate pathway available.
Each Hybrid EMC Absorber can be equipped with two protective end caps. White end caps are 600 x 600mm and help to improve illumination within anechoic chambers. DMAS end caps are available in colors grey and white.
