As a new kind of equipment for electromagnetic compatibility (EMC) testing, reverberation chambers (RCs) have important application value. Probabilistic and statistical model of RCs can be used to describe the EM field environment of RCs. In this paper, some probabilistic and statistical models of RCs are summarized. The model based on mode theory is adopted and a Monte Carlo (MC) method is applied to simulate the EM field environment in a RC numerically. And then the problem of field-to-wire coupling in the RC is considered. Terminated load response of a single wire in the RC is analyzed. The obtained results are consistent with the results obtained by existing solutions. By changing the distances of wire and walls, the field uniformity in the RC is discussed, which implies that the mode-theory-based model can describe the EM environment in RCs in more details.
