Microwave Absorbing Foams


ECCOSORB® AN is a series of lightweight,free space, multi-layer, broadband microwave absorbers. Products are made from polyurethane foam that is treated with carbon and assembled in a laminate construction to generate a controlled conductivity gradient. Each product in the series has it’s own low end cut-off frequency that forms the basis of selection based on operating frequency. Reflectivity reduction is at least 17 dB down for normal incident energy with the correct choice of ECCOSORB® AN absorber.

In situations where the absorber will come in contact with water, fuel, hydraulic fluids, or will be used outdoors, ECCOSORB®ANW is recommended.

Examples for use are radar antenna nacelles, anechoic enclosures, antenna or target test mounts in radar ranges, and inside or outside horn antennas. ECCOSORB® AN can also be used to produce desired modifications in antenna patterns such as the reduction of side-lobes and back-lobes. ECCOSORB® AN is equally effective against linear, elliptical, or circular polarization, and relatively insensitive to incidence angles out to 70 degrees.
