Abstract :
A unique algorithm for time-stepping electromagnetic fields is developed that saves a significant amount of computer resources. It is applied to two-dimensional scattering problems and can be applied to any type of grid and finite difference scheme that uses the Yee time-stepping algorithm. The two-step finite difference equations are reduced to a single step which bypasses many redundant calculations. CPU and memory savings are presented.<>
