Abstract

Invited Paper The FEMAX finite-element package for computing three-dimensional time-domain electromagnetic fields in inhomogeneous media G. Mur Laboratory of Electromagnetic Research, Faculty of Electrical Engineering, Delft University of Technology, PO Box 5031, ABSTRACT An efficient and accurate finite-element package is described for computing transient as well as time-harmonic three-dimensional electromagnetic fields in inhomogeneous media. For the expansion of the field in an inhomoge- neous configuration, edge elements are used along the interfaces between media with different medium properties to allow for the continuity condi- tions of the field across these interfaces, nodal elements are used in the remaining homogeneous subdomains. In the domain of computation the package decides locally what type of element has to be used for obtain- ing the user-specified accuracy of modeling the field. In this way optimum results are obtained both in regard to computational effici
