论文摘要
本文回顾了有限差异时间域（FDTD）模拟中周期性边界条件（PBC）的现状。系统概述了数学原理和3D FDTD实现细节。提出了用于提取散射参数，布里鲁因图和衰减常数的技术，以及用于建模非周期源与周期性结构的相互作用的阵列扫描方法（ASM）。通过这些技术，展示了PBC的鲁棒性，效用和效率，并提出了PBC实施FDTD实施的各种方法的统一观点。
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.
