Coupling of external radiation to circuitry inside complex EM environments

In this paper, we present a hybrid statistical model for confined electromagnetic environments with arbitrary geometry, coupled by electrically wide apertures, in presence of spatially localized sources and sinks. An external (oblique) plane wave is supposed to illuminate the aperture, which radiates inside a wave-chaotic cavity with distributed losses. The dependence of couple voltages on the external radiation is found to take place through a transfer-impedance that is a functional of the hybrid random coupling model. We compute this impedance numerically by the Montecarlo technique.
