Research of the Case of "TM"Incidence including the Peculiar Characteristic of the Magnetic Excitation of Two Slots in a Plane Conductor

研究由横磁场 (TM )激励含两个孔缝的无限平面导体的散射特性 孔缝另一端构成一微波网络 我们用基于格林函数的矩量法计算这一问题 用波导模函数展开未知函数 ,采用伽略金法和三角形基函数 给出了扩展的归一化网络参数 由一平面波激发 ,通过求解归一化网络参数和散射场的场强模式计算 ,给出几组不同参数情况下的散射圆图和数值结果 一些计算实例可以和“TE”情况进行比较

This paper discusses the transverse magnetic(TM)excitation of two slots in a plane conductor terminated by a microwave network.The moment method is used to solve the problem.First,the wave guide mode functions are used as expansion functions.Then,Galerkin's method with triangle basis functions is used.This method of decomposition makes it easier to implement the computation to parallel architectures.The solution is given in terms of generalized network parzameter.Some examples are given and the comparison of the TE case is made.
