SOMINT: An Improved Model for Studying Conducting Objects Near Lossy Half-Spaces.

Abstract

This report summarizes the development of a moment-method numerical code to study wire antennas near lossy earth. The computation time of this code is greatly reduced by two new methods for evaluating the Sommerfeld integrals. In the evaluation of the integrals off the earth, a bivariate interpolation scheme on a prestored grid is shown to give very quick and accurate results. A new series solution is presented to evaluate the integral for values near the interface. Test results of this program are given, along with extensive numerical data on vertical half-rhombic and sloping V antennas. (Author)
