Characterizing reverberation chambers by measurements of the enhanced backscatter coefficient

Reverberation chambers (RC) are becoming a popular alternative testing facility for a wide range of electromagnetic applications. In order for these tests to have any meaning, we need to ensure that the RC is performing in a desired manner. One common approach for characterizing the RC is based on a measurement of field uniformity in the chamber. In this paper, we present an alternative technique for characterizing a RC, based on the enhanced backscatter coefficient (a quantity analogous to the enhanced backscatter that has been derived for scattering by a random medium) measured in the chamber.
