Abstract

Numerical modeling of frequency-modulated (FM) radio-pulse propagation in plasma in focal regions of three-dimensional catastrophe types is fulfilled. As it was shown by D.N. Chystyakov et al.(see Proc. Progress in Electromagnetics Research Symp., p.1085, 2000) and A.S. Kryukovsky et al. (see Jour. of Communications Technology and Electronics, vol.44, no.4, p.423-30, 1999), the catastrophes with corank equal three describe mutual space-time (ST) focusing of electromagnetic waves. In dispersive media, the propagation of an FM electromagnetic wave may be described by an integral uniform asymptotic solution of the Klein-Gordon equation.
