Abstract

Considering either a quantum effect or an electron spin resonance to formulate the interaction of an Electromagnetic Missile with matter, we compared the localized absorption of electromagnetic energy. We took into account temporal shapes of E-M pulses (a gaussian double derivative function: D.S.G) typically generated by new types of picosecond optoelectronic devices (Photo Conducting Pulsed Switching). For ultrashort time of interaction, the electronic transitions undergo a periodic perturbation governed by a non- sinusoid time relationship introducing a square-time function in agreement with the perturbation non-relativistic theory. We attempted to compute numerically the material E-M properties in the case of ultra-wideband pulses with coherence limit considerations. We studied the influence of the frequency spectrum on the ultrashort photoconductivity phenomena induced into semi-conductor materials by such type EM pulses train.
