Integration of Known Unknowns and Unknown Unknowns in Statistical Electromagnetic Coupling

As recognized by many scientists and engineers in the EMC/EMI research community, the physics of external RF sources coupling to electronics inside enclosures is extremely complex and stochastic in nature. It often involves different levels of uncertainties, including RF waveform and engagement angle, system-specific couplings, electronic types, and target configurations. Often at times, we may not have detailed target information (cable bundle characteristics and routing, loading object characteristics and locations, etc.). On the other hand, the coupled EM fields inside target enclosures are very sensitive to the exact geometry of the enclosure, the location of internal sensors and electronics, and the operating frequency.
