Design of Chaotic Reverberation Chambers

Deforming the geometry of a rectangular reverberation chamber (RC) improves the field disorder and the chaoticity of the RC field, even in presence of traditional stirring mechanisms. We study how position and number of hemispherical wall diffractors affect the transmission-based modal overlapping of a real life RC facility. Numerical full wave finite-difference time-domain simulations were performed in order to evaluate the average field transmission over a broad frequency bandwidth.
