Exponential correlation model for electric field intensity in reverberation chambers

The role of field correlations in the intrinsic measurement uncertainty in reverberation chambers (RC) is a topic of great interest for many electromagnetic compatibility as well as over-the-air measurement techniques. This paper investigates the applicability of an exponential correlation model to measured electric field intensities in a RC under different loading conditions. The exponential model allows for a robust estimation of the average correlation in measured data, which is a key parameter for quantifying measurement uncertainty.
