Title: Analysis of wire antennas in the presence of a conducting half space. Part III. The buried antenna

Abstract

The report extends an earlier one dealing with the reflection coefficient approximation (RCA) for modeling objects located near an interface between electrically different half spaces. The procedure to handle objects on opposite sides of the interface is described. The method, which is denoted as the transmission coefficient approximation (TCA), is based on a ray-optics formulation and an assumed reciprocity along a given ray path. An integral-equation, moment-method technique for wires, when combined with the RCA-TCA, permits modeling the response of antennas above ground to buried objects. Similar problems of geophysical interest, as well as those of the more conventional antenna interface, may also be modeled. Sample results to illustrate how the technique may be applied are presented. A comparison of results is made between the RCA-TCA and those obtained from a rigorous treatment based on the Sommerfeld integrals to demonstrate the validity of the approximate approach. The approximate approach offers much greater efficiency (approximately 50 times faster) relative to the rigorous approach.
