EMC Hybrid & Microwave applications
One of the most obvious and important components of anechoic chambers is the RF absorber. Our closed cell, carbon loaded polystyrene absorbers are specifically designed to inhibit the reflection of electromagnetic radiation, which makes them suitable for use in EMC test laboratories as well as antenna chamber applications. Naturally, the absorption characteristics can be altered by using different thicknesses and arrangements. Our absorber products are divided in two main categories: Hybrid & Microwave.
Hybrid chamber solutions make use of ferrite tiles in combination with our HT series of absorbers. Typically for antenna pattern measurement related research our Microwave absorbers can be used. Consult the links at the bottom of this page for details on a specific category or check our brochures online.
Green and sustainable
Our closed cell polystyrene absorbers don’t contain poisonous fire retardant chemicals. They are therefore sustainable, environmentally friendly and fully compliant with REACH and RoHS directives.

More about our polystyrene absorbers
All polystyrene RF absorbers are manufactured by our sister company, Dutch Microwave Absorber Solutions, also known as DMAS. We rely on DMAS absorbers since it’s introduction back in 2012.
Together we achieved great heights by completing many projects using polystyrene absorbers for both EMC and Microwave frequency testing applications.
