Advanced ElectroMagnetics, Inc. (AEMI), developed the Absorbing Wall Module, which can be used within the cavity to absorb interfering signals on a selective basis, in order to help reduce moding problems. Basic features include portability which by simple movement will change moding conditions with changing frequencies.
The Absorbing Wall Module also eliminates moding hot spots and resonances while providing good wide angle performance. The use of EM materials for the modules provide low frequency performance, which will accommodate MIL-STD 461/462 applications.
The wall module is constructed by applying absorber materials to 24 gauge sheet metal. This permits increased efficiency in absorbing characteristics and also allows the user to shield the test environment from personnel or equipment behind the wall modules.
