Abstract

A finite-element method is presented that has been specially designed for the computer modeling of three-dimensional time-harmonic electromagnetic fields in arbitrarily inhomogeneous media. For this purpose, two types of elements have been constructed. In the domain of computation the corresponding program decides locally what type of element to use for obtaining the best results as regards both computational efficiency and accuracy. Numerical results are presented that demonstrate the method to be efficient as well as accurate
