Abstract :
This paper proposes a new technique (explicit technique, yet unconditionally stable) for 2D FDTD algorithm. This method is not limited by the Courant-Friedrich-Levy (CFL) condition and is unconditionally stable beyond the CFL limit; though this is an explicit method. Here numerical formulations are presented and simulation results are compared with other FDTD algorithms.
