摘　　要：传输线矩阵(TLM)是一种强有力的时域和空域电磁场数值仿真算法,它的出现在各个领域引起了广泛关注。文中在简单介绍TLM原理后,对方波导的截止频率用Matlab语言进行编程计算,计算结果与理论计算值吻合。基于Huygens波传播模型的传输线矩阵方法与计算机结合起来后,成为一种强有力的时域电磁场数值仿真算法。The TLM method is a powerful and flexible tool for numerical analysis of wave propagation in time-domain simulations, which has attracted much attention in many fields since its appearance. After a brief introduction to the principle of TLM, the cutoff frequencies of different modes in square-section waveguides are calculated by TLM in matlab and the calculated result agrees with the theoretical result. TLM, which is based on the theory of light propagation originated by Huygens, has developed into a powerful algorithm for numerical analysis of EM wave propagation in time-domain simulations.
