Simulation of Electromagnetic Fields at Sharpening of the Impulse Front in Nonlinear Dielectric

Abstract

An approach to mathematical modeling of electromagnetic waves propagation through inhomogeneous media with non-linear parameters is described. The problem was formulated in terms of the modified vector magnetic potential with regard of magnetic and electric losses. The results of mathematical modeling of electrophysical processes accompanying an electromagnetic wave front sharpening as it propagates through ferroelectric media with nonlinear dependences of permittivity on the level of the electric field strength are presented.
