Abstract :
The Courant-Friedrichs-Lewy (CFL) condition has been recognized and used as a condition that ensures stable time-domain electromagnetic simulation using explicit march-in-time numerical methods. In this paper, using the FDTD (finite difference time domain) method as an example, based on the eigen analysis of the root cause of numerical instability, we propose an explicit wave-equation based FDTD method for solving electromagnetic problems.
