Comparative susceptibility study of pulse and constant amplitude illumination of wires over ground planes

Abstract

Previous studies have shown the predicted voltage that can be impressed across a load when a wire over ground is illuminated by a constant amplitude plane wave. This study extends that work to the case of a wire over ground illuminated by a radar pulse. Three different pulsewidths are studied, 1 mu s, 100 ns, and 10 ns. It is shown that the two types of illumination are quite similar in their effect, with the major difference appearing at the radar signal frequency. As a final comparison, constant amplitude and pulse illumination are compared with illumination by a lightning-like pulse.<>
