Numerical treatment of the spatio-temporal electromagnetic beam-wave packet

¼ubomír Šumichrast – Jaroslav Franek

   Propagation of a two-dimensional spatio-temporal electromagnetic beam wave is analysed. In parabolic (paraxial) approximation the exact analytical results for a spatio-temporal Gaussian impulse can be obtained. For solution of the full wave equation the numerical simulation has to be used. The various facets of this simulation are discussed here.

Keywords: electromagnetic wave-packet propagation, parabolic approximation, numerical modeling
