Abstract

The well-conditioned electric-field integral equation (WEFIE) involves hypersingularity, which makes the numerical implementation of the WEFIE difficult and complicated. A simple and efficient numerical implementation of the WEFIE is presented in this paper. It is proved that the well-conditioned property of the WEFIE is kept in this numerical implementation. Numerical experiments demonstrate the accuracy, efficiency, and stability of the presented implementation approach, even at low frequencies. The effect of round-off errors to the efficiency is analyzed, especially at very low frequencies. The numerical performance of the WEFIE for open bodies is also presented at the end of the paper.
