Reducing the Setup Time of a One-Step FDTD Method

As society places greater demands on technology, it becomes increasingly important to be able to simulate that technology. While simulation tools can be very sophisticated and capable of handling very complex devices and structures, the cost paid in computation time can be prohibitive. To reduce this time, a number of one-step schemes have been developed, but these schemes suffer from a setup time that can outweigh the benefits of the scheme. We examine parallel processing is one means to reduce the setup time. By approaching FDTD from the modal analysis perspective we offer an alternative to implement a one-step scheme for FDTD with coarse-grain parallelization.
