In this paper, new simpler optimization parameters for the nonstandard FDTD (NS‐FDTD) method are proposed by redefining the spatial‐difference operator. Consequently, the number of optimization parameters required in the method is reduced to one from two in 2D space, and three from nine in 3D space, respectively. In addition, it is shown that the NS‐FDTD method using new optimization parameters has more accurate characteristics than the NS‐FDTD method using conventional parameters. © 2005 Wiley Periodicals, Inc.
