Simulation of stirred fields within a reverberation chamber using a refined spectral-domain-factorization moment method

A cavity Green´s function moment method has been implemented using the recently introduced spectral domain factorization that dramatically reduces the cost of treating electromagnetically large chambers. The mixed potential form of the EFIE is implemented here, avoiding the strong singularities in the electric-field Green´s function formulation of the original implementation. The method is used to test the stirring effectiveness of a simple mechanical tuning scheme implemented in an attempt to minimize the number of unknowns that must be used to realistically simulate the fields in a large reverberation chamber. The results confirm that the field statistics can be accurately and efficiently found using the cavity moment method with spectral domain factorization.
