Abstract

© 2015 IEEE. The Statistical Energy Analysis (SEA) is a statistical approach employed to solve high frequency problems of electromagnetically coupled reverberant cavities at a reduced computational cost. The key aspect of this approach is to avoid solving Maxwell's equations inside the cavity, using the power balance principle, which leads directly to the ensemble mean response of the system. In addition, the SEA gives an estimate of the standard deviation of the cavity's energy. Moreover, the diffuse field reciprocity formula is used to calculate the coupling coefficient induced by an aperture, which is neither electrically small nor large. The numerical results obtained for two rooms coupled through a circular aperture are compared with experimental data obtained in the reverberation chamber at IETR. After a brief introduction of the motivation for such a method, the SEA equations are presented, and then the experimental setup is described in section III. Finally, the good agreement between simulation and experiment is presented in section IV.
