“…FDTD PBCs hold irrespective of the contents of the unit period. PBCs have been shown to work in skewed domains [26], [27] and dispersive domains [28]. They also have been successfully applied to triangular FDTD meshes [5].…”

This paper reviews the state of the art of periodic boundary conditions (PBCs) in Finite-Difference Time-Domain (FDTD) simulations. The mathematical principles and 3D FDTD implementation details are systematically outlined. Techniques for extracting scattering parameters, Brillouin diagrams and attenuation constants are presented, along with the Array Scanning Method (ASM) used to model the interaction of non-periodic sources with periodic structures. Through these techniques, the robustness, utility and efficiency of PBCs are demonstrated and a unified view of the various approaches to the FDTD implementation of PBCs is presented.

“…In [8] it was proven that changing the grid of the FSS changes its frequency response and the FDTD results were confirmed by frequency domain simulation results. The design and the analysis are done using the FDTD/PBC algorithm described in [8], which is based on the constant horizontal wavenumber approach [9][10][11][12][13][14][15]. The diode is simulated using the actual diode currentvoltage equation for forward bias, while using a circuit model consisting of resistor and capacitor in parallel for reversed bias in the presence of both axial and skewed FSS grids, which provides more accurate simulation results compared to simulating the diode as an open circuit (OC) for the OFF state and a short circuit (SC) for the ON state [16].…”

Abstract-Novel reconfigurable frequency selective surfaces (RFSS) are designed using a finite-difference time-domain with periodic boundary condition (FDTD/PBC) algorithm.The FSS are reconfigured using two techniques: the first technique providing a wide frequency tuning range is based on using diodes to change the current distribution over the FSS surface, and the second technique exhibiting a finer frequency tuning resolution is based on changing the grid orientation of the FSS mechanically. Simulation results are provided to validate the concept of RFSS. The results show that these designs provide a wide dynamic range of reconfigurability and a large degree of freedom in controlling the FSS frequency response.
