A Statistical Method for Prediction of Port in Wave-Chaotic Cavity

This paper discusses the wave chaos phenomena within cavities under high-power microwaves. Addressing this phenomenon, the random coupling model is employed to statistically analyze the coupling of ports inside the wave chaotic cavity generated by high-power microwaves. Particular emphasis is placed on microstrip line considerations. Using the KronBranin model, the average absorption cross-section of microstrip line structures under the random plane waves hypothesis is calculated. This calculation facilitates a statistical prediction of the coupling scenarios among microstrip lines within the wave chaotic cavity. Furthermore, experiments are designed utilizing a monopole antenna as a reference port and microstrip lines of varying lengths as the ports under consideration, thus validating the reliability of this methodology.
