​​ETS-Lindgren's type EHP (Extra High Performance) microwave absorber is designed for use over a wide frequency spectrum and has been used as an effective tool for the reduction of reflections from 30 MHz through 100 GHz. Each piece of absorber is fabricated of the highest quality urethane foam, which is cut into a precise bun configuration and impregnated with a conductive carbon using a proprietary formulation. 

Whether you need just a few pieces of absorber or a complete turnkey chamber, we have the experience and resources to help you with the right solution.
