Various simulation techniques are examined which are considered feasible means to reproduce the external surface currents on satellite structures which result from system generated electromagnetic pulses (SGEMP). These techniques include (a) plane wave excitation, (b) monopole near-field excitation, (c) hardwire current injection excitation, and (d) charge injection excitation using a small self-contained pulser. The simulation effectiveness of each of these techniques, based on the ability of the simulation method to reproduce surface currents comparable to those predicted for generic SGEMP excitation, is explored. The conclusions from this investigation are: (1) the monopole excitation technique produces responses that simulate most favorably those predicted for the SGEMP excitation; (2) either current injection scheme will produce responses comparable to those predicted for local electron emission excitation provided the excitation scheme is sufficiently decoupled from the satellite; and (3) plane wave excitation produces responses that are significantly different, both in the peak magnitude variation around the satellite body and in the frequency content of the pulses, from those predicted for SGEMP.
