摘要
时域有限差分法是麦氏方程的差分形式的数值解法,可用于求解任意复杂目标与电磁场的相互作用问题。本文讨论了该方法的基本原理及实现过程中的一些技巧性问题。在稳态时谐场问题中引入了复场量算法。最后,给出了一些计算实例。
FDTD is a numerical method to seek the solution of Maxwell equations by marching in tihme domain, which can be used to analyze the interactions between electromagnetic fields and complicated objects. The fundamentals of FDTD are discussed in this paper, and some useful skills introduced. In particular, complex field components are used in time-harmonic case in order to obtain smooth output for phase. Finally, some examples are provided.
