Sustainable, high performance and finished with the signature javelin tip.
Over The Air (OTA) Testing / Near Field testing / Compact Antenna Test Ranges
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.
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.

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.

DMAS polystyrene absorbers are designed and manufactured in The Netherlands to ensure the highest levels of quality.
DMAS enjoys a close collaboration with Comtest Engineering, one of the foremost suppliers of anechoic chamber solutions. Together, we have over 45 years of experience in the field.
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.
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)
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.
Looking for the very best in RF absorbing technology? DMAS microwave absorbers are designed for modern testing facilities and offer excellent performance as well as a long product life. Contact us today to learn more about DMAS microwave absorbing material.
