Abstract

The conventional electric field integral equation (EFIE) is augmented by including charge as the extra unknown, so that the contributions of the vector potential and the scalar potential are separated to avoid the imbalance at low frequencies. With the frequency scaling and the direct enforcement of the current continuity constraint, the new augmented EFIE is free of low-frequency breakdown for interconnect analysis. Mathematically, it can be categorized as a generalized saddle-point problem. The new equation is verified by numerical examples.
