Electromagnetic Transmission through a Rectangular Aperture in a Perfectly Conducting Plane

Abstract

A computer program is developed for calculations the transmission characteristics of a rectangular aperture in a perfectly conducting plane excited by an incident plane wave. The solution is obtained from the integral equation for the equivalent magnetic current using the method of moments. The expansion functions and testing functions are pulses in the direction transverse to current flow, and triangles in the direction of current flow. Quantities computed are the equivalent magnetic current and the transmission cross section patterns. To illustrate the solution, computations are given for narrow slots and for square apertures. The computer program is described and listed with sample input-output data.
