Bounding EMP interaction and coupling

A technique is presented for obtaining upper bounds of the voltages and currents at terminations on a wire which is excited by an incident electromagnetic wave coupled through an aperture. The internal interaction and coupling problems are considered. Upper bounds are developed for the power waves launched on the wire structure and the termination signal levels are bound with a term included for multiple reflections. Tighter bounds are obtained by separating the incident field into individual parts typically characterized by poles in the complex frequency domain.
