摘要

The random coupling model (RCM) has been successfully demonstrated to characterize the statistics of the impedance matrix for complex multi-port cavities. However, a challenge remains in finding a practical method to measure the necessary parameters that form the model, especially in the case where ports have localized power loss. In this paper, we present practical methods to measure the radiation impedance of the port and the loss parameter of the cavity. In the case of lossy port in the complex cavity, a generalized antenna model is adopted, and the radiation efficiency of the antenna is used to modify RCM's impedance description.
