ECCOSORB® ANW is a series of lightweight, free space, multi-layer, broadband microwave absorbers which can be used outdoors or in situations where the absorber will come in contact with fuel, lubricants, or hydraulic fluids. 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 20 dB down for normal incident energy with the correct choice of ECCOSORB® ANW absorber.
Examples for use include radar antenna nacelles, anechoic enclosures, antenna or target test mounts in radar ranges, and reducing reflections from buildings on antenna ranges. ECCOSORB® ANW can also be used to produce desired modifications in antenna patterns such as the reduction of side-lobes and back-lobes.
Should ECCOSORB® ANW need to be cut or trimmed, this may compromise its effectiveness for outdoor applications. A special neoprene coated fabric called ECCOSORB® 86B tape is available in conjunction with ECCOSTOCK® 13-111-NF adhesive to reseal exposed edges or attach this material to a surface.
