We describe an efficient solver for the potential formulation of Maxwell's equations, defined by the Lorenz gauge. Our method is based on constructing fast convolution algorithms for semi-discrete boundary integral solutions to the wave equation. Using an alternate direction implicit (ADI) splitting, we achieve an O(N), A-stable and second order accurate(More)
The Convected Scheme (CS) is a family of semi-Lagrangian algorithms, most usually applied to the solution of Boltzmann's equation, which uses a method of characteristics in an integral form to project a moving cell (MC) forward to a group of mesh cells. In earlier work [1], a 4th-order version of the cell-centered CS was presented, which was based on(More)
