Profile: Advanced ElectroMagnetics, Inc. manufactures a range of RF absorbing material. The industries we serve include military, aerospace, satellite, EMC and telecommunications industries. Our standard RF absorbers from 30 MHz to 100 GHz are for use in anechoic chambers. These facilities are test environments for electromagnetic interference control (EMI), compatibility (EMC), radar cross section (RCS) and general purpose antenna measurement capabilities. Our broadband walkway RF absorber is composed of a self-extinguishing polystyrene core placed in an interlocking pattern over a standard AEP type material. This structure is topped with a higher density polystyrene laminate. Anechoic chambers are necessary to suppress any reflections that could disturb the measurements of antennas or equipments in the microwave frequency range. we can build chambers of standard dry wall ordry wall with foil or welded shielding (up to 120 dB of isolation).
