ECCOSORB® AN - Flexible Foam Sheet Broadband Microwave Absorbers

• Lightweight, flexible, broadband, open-cell foam absorber
• Carbon loaded, laminated polyurethane sheets
• Frequency range from 600 MHz to 40 GHz
• Designed to reflect less than -20 dB of normal incident energy above specified frequencies and relative to a metal plate
• Does not support fungal growth per MIL-STD-810E
• Can be readily cut on a band saw, with scissors, or a sharp knife

Environmental Properties

• ECCOSORB® AN is not waterproof and will not operate correctly when wet. Since there is no washout, ECCOSORB® AN will function as expected after being allowed to dry
• A special CERSEAL coating to prevent moisture uptake in high humidity to moderately wet environments is available on special request
• For waterproof applications, see ECCOSORB® ANW or ECCOSORB® AN can be coated with CERSEAL

• ECCOSORB® AN has been used in reducing crosstalk between adjacent antennas, shrouding antennas to improve the antenna patterns and undesired backlobes, as well as selective shadowing of parts of a target for RCS measurements
• Shadowing of posts and supports in anechoic chambers, and as absorbing blankets for testing radar systems without harm to personnel
• ECCOSORB® AN is also effective in reducing surface current waves on metal shapes
• For isolation of components or antennas by means of insertion loss, it can be used without a metal backing
