Abstract :
We present a parameter optimized alternating-direction implicit (ADI)-finite-difference time-domain (FDTD) method. This parameter optimized ADI-FDTD algorithm can minimize the dispersion error for arbitrary incident angles and for different time-step sizes. Stability analysis shows that this algorithm is unconditionally stable if proper parameter values are chosen. Dispersion analysis illustrates the reduced dispersion error of this algorithm.
