Influences of loading absorber on the performances of a reverberation chamber

Abstract

This paper studies in detail the loading effect on the performances, especially independent sampling points in a reverberation chamber. Different amounts of absorbers have used to load the chamber and the average power over one revolution of tuner sweeping has been used to quantify the improvement of performances versus sacrifice of average electric field. The influence of locations of absorbers relative to transmitting antenna and stirrers on performance has also been studied. It is found a suitable amount of absorbers placed at appropriate positions may increase the performance of a chamber better than more absorbers placed improbably.
