Abstract

The Numerical Electromagnetic Code (NEC) is one of the most popular tools for electromagnetic simulation of wireframe structures. The application of NEC is often limited to small to medium sized problems due to its full matrix nature. In this paper, an approach by using the wavelet transform to increase the efficiency and capability of NEC is presented. In the approach, a sparse moment matrix equation can be produced and solved by efficient sparse solver instead of solving full matrix equation in the original NEC. Under close examination, structures with less singularities are found to have much better accuracy and higher compression rates
