The dependence of the model density characteristics on the chamber geometry is discussed, for general unstirred reverberation chambers and relatively low frequencies of operation. An expression for the lowest usable frequency based is derived on the mode density. The use of curved wave diffractors is investigated as a method for increasing the average mode density. The specific effect of corner, edge, surface and volume diffractors on the mode density and quality factor of a nominally rectangular shielded room is analyzed as a function of diffractor size and frequency. The present work complements earlier studies on field statistics of undermoded reverberation chambers and performance of acoustic-type diffusors in electromagnetic reverberation chambers.
