Electronically reconfigurable reverberation chambers

The idea of an electronically reconfigurable reverberation chamber (ERRC) is introduced, whose purpose is to support over-the-air (OTA) testing in a compact and cost-effective way. In contrast to mechanically stirred chambers, the ERRC operates by randomly varying reconfigurable loads placed on the walls of the chamber. An idealized two-dimensional structure is analyzed revealing that the fading distribution, spatial correlation, frequency selectivity, and multipath directivity can be controlled by proper specification of the random loads.
