Abstract :
Compared to the conventional FDTD, the WCS-FDTD can employ much larger time step while the high order methods can use larger space step without losing accuracy. In this paper, we incorporate the high order method into the largest dimension of the WCS-FDTD. The modifications of the updating equations are derived. The numerical example proved that the proposed method can employ larger time step than that of the WCS-FDTD while get better accuracy.
