In this reort, a new algorithm for two-dimensional(2-D)finite-different time-domain(FDTD)is presented. By this new method, the maximum time-step size can be increased over the Courant-Friedrich-Levy(CFL)condition restraint. This new algorithm is adapted from an Alternating-Direction Implicit FDTD(ADI-FDTD)method. However, unlike the ADI-FDTD algorithm, the alternation is performed with respect to the blocks of fields rather than with respect to each respective coordinate direction. Moreover, this method can be efficiently simulated with parallel computation, and it is more efficient than the conventional FDTD method in terms of CPU time. Numerical formulations are shown and simulation results are presented to demonstrate the effectiveness and efficiency of our proposed method.
