Abstract
The first two moments of the wave power transmitted in time-reversal invariant system having ergodic motion was studied using random matrix theory (RMT). A number of loss channels of variable coupling strength were used to model the dissipation. The quantities of interest Were calculated by employing the supersymmetry technique within the RMT model. The results of the supersymmetric method were confirmed by Monte carlo numerical simulation and used to reveal a possible source of the disagreement between the predictions of the naive theory and ultrasonic measurements.
