An efficient hybrid method is developed for calculating the coupling to a device on a printed circuit board inside a cavity. The printed circuit board is connected to a wire or cable that penetrates an aperture in the cavity enclosure. The method uses a combination of transmission-line analysis and a full-wave solver, and a decomposition of the problem into interior and exterior problems for maximum efficiency. Results are presented to verify the accuracy of the proposed method and to study the effects of cavity resonances on the coupling to a device inside the cavity.
