二维目标电磁散射瞬态响应的TLM方法模拟

Simulation of the Transient Response of 2-D Objects to the TM Electromagnetic Wave by TLM Method

运用传输线矩阵（TLM，transmission－linematrix）方法研究二维特殊形状理想导体目标对电磁波的瞬态响应。数值结果表明，TLM方法对于电磁散射问题的数值模拟不仅很方便而且实用，尤其对于较为复杂的目标（形状特殊，成分复杂），方法本身不需要作任何改变，只需改变网格划分便可以进行计算。

In this paper, TLM(Transmission Line Matrix)is used for the simulation of the transient response of 2-D objects which are of special forms to the TM electromagnetics. Numerical results indicate that the TLM method is very convenient to be applied to the problems of EM scattering, especially for the complex objects(special form and material).
