GTD-AMP Computer Program Description. User's Manual.

Abstract

This report describes the capabilities, limitations, and operation of the OSU, GTD-AMP Computer Code, which has been developed to calculate the electromagnetic radiation from currents on thin wires in the presence of a perfectly-conducting polygonal plate positioned over a reflecting surface of infinite extent. Although the code is based on the Geometrical Theory of Diffraction (GTD) it is designed to be compatible with the Antenna Modeling Program (AMP). The GTD-AMP program described herein is capable of handling many antenna-scattering problems once the currents on the wire radiators are known. Ordinarily these currents are found from the AMP program in the manner described in the text; however, they may be specified or obtained by other means. This combination of the moment method and GTD makes it possible to calculate radiation patterns which could not be calculated by either method individually.
