Abstract This report describes a novel implicit solver method for modeling electromagnetic interactions in the time domain. It is designed to outperform finite difference time domain (FDTD) on EM modeling problems with fine spatial detail. The method is novel in that it computes electric and magnetic potentials rather than fields and in the way it efficiently solves a large, sparse system of linear equations at each time step using a fast, multi-grid Laplace solver. We describe the method and present results from our numerical implementation.
