Abstract

A conventional reverberation chamber has a rectangular structure including mode-stirrers or mode-tuned stirrers to obtain the field uniformity inside the chamber. In this paper, we used Schroeder diffusers to obtain field uniformity of a rectangular reverberation chamber, and field uniformity characteristics were investigated with the condition of diffuser volume ratio of 0.9, 1.35, and 1.8 % of the total rectangular empty volume. The Finite-Difference Time-Domain (FDTD) simulation method was used to analyze the field homogeneous characteristics of these reverberation chambers
