摘要

本文从理论上和定性上比较了两种最流行的电磁问题时域数值分析方法:传输在线建模(TLM)法和时域有限差分(FDTD)法。这种比较是基于作者和其他人的经验。TLM是基于惠更斯原理的物理模型，使用互连的传输线，而FDTD是直接基于麦克斯韦方程的近似数学模型。

A comparison of finite difference time-domain (FDTD) and transmission-line modeling (TLM) methods

This paper presents both theoretical and qualitative comparison of the two most popular time-domain numerical methods for the analysis of electromagnetic problems: the transmission-line modeling (TLM) method and the finite-difference time-domain (FDTD). The comparison is based on the author's experience as well as others. While TLM is a physical model based on Huygens' principle using interconnected transmission lines, the FDTD is an approximate mathematical model directly based on Maxwell's equations.
