Abstract

Parameters of the perfectly matched layer (PML) for 2D magnetic field in a region bounded by circular boundary are rigorously calculated for the case of symmetrical or antisymmetrical boundary conditions. The PML consists of a single or double layer of elements, whose artificial parameters are calculated by minimizing an error function of potential difference between the nodal potentials of the PML and of the original grid expanding to infinity.

Abstract

A new finite element method (FEM) approach is used to evaluate transient electric field based on a surge wave in a dissipative open region. Instead of the solution of the basic equations in the time domain, the Laplace transform inversion is used to model planar and axisymmetrical transient fields. The main advantage of this approach consists in the possibility of modeling unbounded regions. Current‐driven electrodes, including electrodes with floating potential, are taken into consideration.
