Finite-Element Method for the Modeling of Electromagnetic Fields Using Generalized Cartesian Elements.

摘要

This paper presents a new finite-element method for the modeling of three-dimensional electromagnetic fields in inhomogeneous media. For the accurate and efficient modeling of the field along interfaces between media with different constitutive parameters, the family of generalized Cartesian finite elements is applied that replaces the commonly used edge elements. A simple numerical example demonstrating the use of generalized Cartesian finite elements when applied to stationary magnetic fields is presented.
