Transient analysis for electromagnetic exciting to a wire through a slot in a conducting screen

Abstract

A method of solution and some results for the electromagnetic transient current response of a finite-length wire due to a transient planar wave excitation through a slot aperture are obtained using the singularity expansion method (SEM). The pertinent SEM parameters are calculated. The equivalent transient magnetic currents in the slot region and the transient electric currents on the wire are found as functions of time for a step electromagnetic excitation.<>
