An experimental study is performed on electromagnetic time reversal in highly scattering environments, with a particular focus on performance when environmental conditions change. In particular, we consider the case for which there is a mismatch between the Green’s function used on the forward measurement and that used for time-reversal inversion. We examine the degradation in the time-reversal...
