Spectral Domain and FFT Accelerated Cavity Green's Function Boundary Element Methods for Numerical Modeling of Reverberation Chambers

157 Seiten, Dissertation Technische Universität München (2016), Hardcover, A5

Zusammenfassung / Abstract

A boundary element method with the Green's function of the rectangular cavity is presented 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 to 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.
