A Simple Model for Estimating SGEMP Replacement Currents and Evaluating SGEMP Simulation Difficulties

Abstract

This report describes a simple method for roughly estimating SGEMP replacement currents, given the electron emission current. The method assumes immediate charge redistribution and uses the continuity equation to obtain an expression for skin currents on a sphere. This simple model is then used to calculate replacement current distributions when only a discrete number of drive locations are used to simulate excitation of an entire surface. It is indicated that unrealistic current distributions will result in the areas between drive locations on surfaces that are supposedly emitting electrons.
