Abstract:
This work presents an approximate frequency
domain mathematical model based on the transmission line
(TL) theory for field-to-wire coupling in a rectangular metallic
enclosure. The currents and voltages at the terminations of a
TL induced by known electromagnetic (EM) field sources are
expressed in closed form. Validity limits and applicability of
the model are discussed by comparing the analytical TL-based
predictions with the outputs of a full-wave numerical analysis of
the overall structure using a three-dimensional finite integration
technique. Deviations from the full-wave solution, due to the
scattered field from the TL, have been identified, analyzed,
and discussed. The proposed analytical model proves to be
generally suited for accurate prediction of radiated susceptibility
of single-ended interconnections in closed environments.
