Abstract
Transient testpulses like electromagnetic pulse and ultrawide-band are commonly described by rise time tr, pulse length t fwhm and the maximum amplitude Ê. Simulating the effects of varying pulses an analytical description of the pulses is necessary, which is given by a double exponential form with the parameters α, β and E0. This paper describes the link between the parameters tr, tfwhm and E on the one side and the analytical parameters α, β and E0 on the other side. It is shown that the Nelder Mead Simplex Algorithm in combination with the least squares method is appropriate to determine an analytical relationship between these parameters. There with extensive analysis of double exponential pulse shapes with far-ranging parameters is possible in a considerably smaller computing time.
