ON SOME ASPECTS OF THE COMPLEX-ENVELOPE FINITE-DIFFERENCES SIMULATION OF WAVE PROPAGATION IN ONE-DIMENSIONAL CASE

Ľubomír Šumichrast

   Some aspects of the numerical modeling of the electromagnetic waves propagation using the "complex-envelope" finite-differences formulation in the one-dimensional case are here reviewed and discussed in comparison with the standard finite-differences in time-domain (FDTD) approach. The main focus is put on the stability and the numerical dispersion issues of the "complex envelope" explicit and implicit methods.

Keywords: wave phenomena, computer simulation, finite-differences in time-domain, complex-envelope method
