Uncovering interference paths in complex environments with the random coupling model

The electromagnetic stress onto circuitry inside enclosures is a complicated process made of several coupling paths originated by multiple sources. Those sources are treated as equivalent apertures, and the cavity is assumed to have irregular boundaries. Then, a statistical description relying on wave-chaos theory is more appropriate to describe the coupling process. The Gibbs maximum entropy principle is adopted to derive the probability density function of the single aperture power stressing onto a port arbitrarily located inside the enclosure. Achieved results can be used to estimate the number of coupling paths between interconnected environments.
