Abstract

The inclusion of losses in FDTD codes allows a reliable simulation of actual reverberation chambers. The using of equivalent volumetric losses makes simulations faster than the adoption of equivalent wall losses. In particular, in the case of wall losses the effect of considering a variable wall surface impedance is also analyzed. These different ways to manage RC losses in simulations are compared by analyzing their effects on uncorrelated spatial points and frequency steps. The uncorrelation degree is checked by a multivariate approach based on Pearson's correlation matrix. Results highlight that the volumetric and wall loss methods return similar values for the investigated quantities, so that the more simpler volumetric approach can be successfully applied.
