Double exponential approximation and inverse double exponential fit for Bell Labs and International-Military Standard EMP waveforms

Campione, Salvatore; Warne, Larry K.

We summarize here the double exponential and inverse double exponential approximations for two common EMP waveforms, the Bell Laboratories (Bell Labs) and the International- military standard (IEC-MIL-STD). Both models have been used frequently due to their relatively easy analytical expressions for both the time domain waveforms and their associated frequency domain spectra.
