Field-to-Wire Coupling in an Electrically Large Cavity: A Semianalytic Solution

This paper proposes a semianalytic solution to the problem of high frequency coupling on a wire running in electrically large enclosures. This model is basically derived from the transmission-line (TL) theory in which the electromagnetic (EM) environment, represented as a random plane-wave spectrum, is characterized by its statistical parameters. The results are compared to those obtained by randomly generating elementary plane-wave samples and numerically calculating their EM coupling through a TL model.
