Examining the True Effectiveness of Loading a Reverberation Chamber



Jason Coder, John M. Ladbury, Christopher L. Holloway, Kate Remley


In this paper we explore how placing the same amount of 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 obtained from moving absorber around a reverberation chamber and repeating the same measurement at each location. We conclude with some suggestions to ensure absorber is placed consistently.
