Reverberation chambers deformed by spherical diffractors

Numerical FDTD full-wave simulations are performed in order to evaluate the behavior of a chaotic reverberation chamber. Performances are evaluated in terms of uncorrelated frequencies and antenna positions by using a correlation-based multivariate approach. The chaotic cavity geometry is obtained by including spherical diffractors inside the chamber. It is demonstrated that wall deformations enhance field uncorrelation and disorder within the investigated frequency range, including relatively low frequency of operation, thus assisting source stirring.
