Abstract
A low-frequency stable potential formulation is presented. It covers lossy and lossless regions, results in symmetric finite-element matrices, and guarantees unique solutions. This contribution improves upon the authors’ prior work by including general impressed currents and charge distributions. Moreover, it clarifies the interface condition to be imposed on the gauge on the common boundaries of the lossy and lossless regions.
