Abstract :Numerical dispersion performances of ADI-FDTD and S-FDTD methods have been compared. It has been shown that for time steps below the stability limits of the S-FDTD method it has much better dispersion performance compared with the ADI-FDTD method and that the S-FDTD method can be usefully employed for space increments in the order of l/25 to l/50.Keywords : Symplectic finite-difference time-domain (S-FDTD) method, alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method
