A cavity Green's function boundary element method for the modeling of reverberation chambers: Validation against measurements

Abstract

A hybrid cavity Green's function boundary element method with spectral domain acceleration for the modeling of reverberation chambers is for the first time validated against measurements. The numerical model is optimized for computational speed: geometrical details, such as cables or the stirrer axis, are neglected; the excitation antenna is modeled as a dipole; and losses of the cavity walls and all other objects are approximately handled by complexification of the wavenumber. Despite the coarseness of the model, the numerical results are in good agreement with the measurements for statistical quantities, such as the number of independent stirrer positions.
