摘　　要：广义散射矩阵理论(GSM)基于谱域矩量法,首先将结构剖分成多个独立的个体层,应用谱域法分别计算个体层的散射矩阵,应用网络级联理论得到总的散射参量,用于分析结构的反射和传输特性。文中给出了若干结构的仿真算例,并与其他方法所得结果进行对比,以验证该方法的有效性。The generalized scattering matrix method is based on a spectral moment method. To obtain the overall scattering parameters of the structure, which are used to determine the reflection and transmission properties, a matrix of scattering parameters is evaluated for each individual layer, and then a scattering matrix for the entire structure is formed by a procedure analogous to the cascading of networks iteratively. Several numerical results were presented, comparing with results derived from other methods, to verify the efficiency of the proposed technique.
