An Approximate Solution for the Response of a Sphere in a Tactical EMP Source Region and Estimates of Coupling to an Antenna.

Abstract

Bombardt (1975) has discussed an early time model for the electromagnetic response of a sphere over a guard plane in the presence of source and conduction currents in the air. In this report the formal field solutions from this model are approximately evaluated via contour integration of inverse Laplace transforms. The resulting scattered radial electric field is used to estimate the electromagnetic pulse response of a sphere-mounted antenna. (Author)
