MLFMM-Accelerated Integral-Equation Modeling of Reverberation Chambers [Open Problems in CEM]

The widespread use of reverberation chambers (RCs) is described, and the importance of reverberation-chamber modeling is introduced. Recent developments in reverberation-chamber modeling techniques are then briefly reviewed. It is found that modeling large-scale reverberation chambers is still a challenge. Reverberation-chamber modeling using integral equations, accelerated by the Multi-Level Fast Multipole Method (MLFMM) is discussed. Simulation results are presented to show the performance of MLFMM-accelerated integral equations in modeling reverberation chambers. Finally, challenges in reverberation-chamber modeling using MLFMM-accelerated integral equations are summarized, based on numerical experiments.
