Eccosorb™ AN

Products are made from polyurethane foam that is treated with special filler 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. 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 is equally effective against linear, elliptical, or circular polarization, and relatively insensitive to incidence angles out to 70 degrees.
