Electromagnetic coupling to an enclosure via a wire penetration

This paper presents an efficient model, which can be computed in seconds, for the coupling of external electromagnetic fields to the contents of an enclosure via wire penetrations. The coupling path accounts for the coupling of an external electric field to a wire penetration that establishes an internal electric field via the connect and internal wire segment. The internal electric field then couples onto another victim wire segment, inside the box. The accuracy of the model is demonstrated by the good agreement obtained between predicted induced voltage on the victim wire segment, and experimental measurements
