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.

Features and benefits

Comtest’s absorbers benefit from unique features and enhanced design:

  • Light weight product (40% lighter than traditional foam solutions)
  • Modular design with removable tapers (damaged tapers are easily replaced)
  • Closed cell polystyrene product (no leakage of carbon particles)
  • Uniform carbon cell loading for stable performance throughout the whole product
  • Rigidity and superior tensile strength (no drooping tips)
  • Resilience to humidity (non-hygroscopic)
  • Superior product life (upwards of 40 years)
  • Certified for use in clean rooms (class 10.000 / ISO14644-1 class 4)
  • Compliant with fire retardant standard ISO 11925-2 class E
