A factorial designed experiment for evaluation of mode-stirrers in reverberation chambers

Abstract

A factorial designed experiment at two levels was applied to investigate the performance of stirrers in reverberation chambers. The goal has been to quantify the sensitivity of the design parameters for the mode-stirrer. The focus has been to investigate single rotational stirrers. The experiment shows that the effect of changing the diameter of the stirrer is much greater than changing the height, and that the effect of changing the chamber volume is small
