Abstract

A low frequency stable, surface integral equation method is proposed to solve dielectric and conductor problems. To alleviate the low frequency breakdown, the augmented electric field integral equation (A-EFIE) technique is adopted. We propose the use of Buffa-Christiansen (BC) basis function to represent the magnetic current to eliminate the testing problem. For good conductors, a novel integration scheme is used to accurately capture the coupling of sources and fields for the internal part.
