Distribution of reflection coefficients in absorbing chaotic microwave cavities -: art. no. 174102

The distribution of reflection coefficients P(R) for chaotic microwave cavities with time-reversal symmetry is investigated in different absorption and antenna coupling regimes. For all regimes the agreement between experimental distributions and random-matrix theory predictions is very good, provided both the antenna coupling T-a and the wall absorption strength T-w are taken into account in an appropriate way. These parameters are determined by independent experimental quantities.
