  • In this paper, the FDTD with least square fitting method is used to calculate the S parameters of PBG filter structures, Furthermore, the least square fitting method is employed combined with FDTD to reduce the iterative steps. To show the accuracy of the method, a simulated result is given in the latter part of the paper and various comparisons are made for such a demonstration.
