Abstract

In this paper we explore how placing the same amount of RF absorber in different locations within a reverberation chamber can have different loading effects. This difference can have a significant impact on measurement reproducibility, both for measurements in the same chamber and measurements between chambers (i.e., round robin style testing). We begin by discussing some of the theories behind this and show some experimental results from different absorber placements in a reverberation chamber. Our experimental results will be presented in a fundamental format and in a practical sense (RMS-delay spread). We conclude with some suggestions to ensure absorber is placed consistently.
