Application of edge elements to 3-D electromagnetic field analysis accounting for both inductive and capacitive effects

摘要

The traditional low-frequency eddy-current solvers do not include displacement current effect, while high-frequency solvers do not consider the nonlinearity of material properties. A novel solver for electromagnetic field analysis that addresses both the inductive and capacitive effects is, thus, highly valuable. A stable time-domain magnetic vector potential (MVP) formulation, which includes both the inductive and capacitive effects, is proposed and numerical examples are solved using the proposed formulation. The proposed MVP formulation is very promising in further engineering applications.
