Abstract :
We propose a new electromagnetic simulation method called the sparse finite difference time domain (FDTD) method. It is based on standard FDTD but is faster by approximately an order of magnitude for large waveguide circuits, because it calculates only where significant electromagnetic energy is present. We derive and demonstrate 2-D sparse FDTD.
