The response of nonlinearly loaded antennas to repetitive HPEM excitations as obtained from equivalent circuit models

Abstract

In this contribution the effects of repetitive pulse excitations on linearly and nonlinearly loaded antennas are studied on the basis of equivalent circuit models. In the known linear case, repetitive pulses can lead to an increase of the amplitudes of oscillations. These oscillations decay, if realistic quality factors are assumed, comparatively quickly. In the considered nonlinear case the effects of repetitive pulses can add up and persist along much larger time scales. This remarkable effect has no equivalent in the linear case.
