Analysis of finite periodic structure by FDTD and SOC technique

In this paper, the application of the finite-difference time-domain (FDTD) algorithm combined with the short-open calibration SOC technique to three-dimensional finite periodic structure is presented. We can get the scattering parameters of the whole periodic structure through analyzing only one cell of it. So the combination of the SOC technique and FDTD for finite periodic structures makes the calculation much faster and much more accurate. Results for finite periodic structure are well compared with the conventional FDTD method.
