Abstract

The finite-difference time-domain (FDTD) method has been widely used for the numerical analysis of transient electromagnetic problems because it is conditionally stable and very easy to implement [1]. However, since the FDTD method is an explicit time-marching technique, its time step size should be limited by the well-known CourantFriedich-Lecy (CFL) stability condition. Since the time step is dependent on the smallest length of the cell in a computational domain, this CFL condition may be too restrictive to solve problems with fine structures — thin material, slot, and via.
