Paper Abstract

Using a FFT algorithm, we study the frequency spectrum of EM ultra-short time duration to determine its influence on the propagation properties of such type EM pulse train. We try to perform these properties by taking into account the energy carried in the high frequency part of the spectrum. We attempt to use the temporal shape of pulses generated by new types of picosecond optoelectronic devices (Photo Conducting Pulsed Switching) in the case of flat wave front. For this study, we also consider the same approach as the one described by WU et al. (Harvard University) by applying the theorem of Bessel-Parseval. We try to correlate the slow decay of EM energy with the spectrum structure presented by the EM wave train.
