A boundary element method with the Green's function of the rectangular cavity is presented, analyzed, and employed for the numerical modeling of reverberation chambers. Different from previous work, two approaches, a fast group spectral domain approach and a fast Fourier transform accelerated Ewald summation technique, are presented which relieve the major shortcomings of the cavity Green’s function boundary element method: the large computational burden of the cavity Green’s function in the high frequency regime and the computationally expensive filling of the system matrix.
