摘要

介绍了一种具有非线性参数的非均匀介质中电磁波传播的数学建模方法。这个问题是用考虑磁损和电损的修正矢量磁势来表示的。给出了伴随电磁波锋面锐化的电物理过程的数学建模结果，因为它在铁电介质中传播，并且介电常数与电场强度水平呈非线性关系。

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

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.
