Numerical contribution for time reversal process in reverberation chamber

In this paper, the TR method has been applied in electromagnetism. Theoretical results were compared with numerical data from an FDTD code. Different simulations in a reverberation cavity helped to establish the link between modal density and focusing quality (through the STN ratio). It has also been demonstrated that addition of diffracting objects in a reverberation chamber increases the signal to noise ratio of TR focusing. Thus, the TR paradigm developed in this paper may help to characterize the stirrer in another way, differing from classical statistical standards in RC.
