A simple model for the analysis of microwave propagation in coupled complex cavities is presented. The cumulative build-up and full exchange of electromagnetic energy between coupled spaces are important issues for wireless systems in reverberant environments, such as below-deck compartments in ships and aircraft cabins and bays. Based on conservation of average energy in the steady state among multiple cavities, the general model formulation is valid for both strong and weak couplings between the cavities caused by window materials, open apertures, closed and open hatches, and cable/pipe penetrations through bulkheads. Application of the model is demonstrated in conjunction with measurements conducted in nested reverberation chambers in the laboratory and in the coupled main weapons bays of a fighter aircraft.
