Electromagnetic coupling to an infinite wire through a slot in a conducting plane

The Problem of electromagnetic coupling through a slot-perforated conducting plane to an infinitely long wire is considered. It is treated as a boundary value problem and is formulated by use of the equivalence principle and image theory as a pair of coupled operator equations. The operator equations are solved simultaneously by means of the method of moments. The equivalent magnetic current on the slot and the electric current on the wire are obtained. The equivalent circuit seen by the transmission line mode on the wire is derived for the aperture-to-wire coupling system. Computer programs for solving this problem are presented and described. Some numerical examples are given and plotted.
