This paper presents the combination scattering-matrix method and wave iterative computation (WIC) for complementary split rings resonator (CSRR) based band pass filter analysis. The WIC is a numerical model for analyzing the electromagnetic problems of microwave and millimeter-wave circuits and systems. The scattering matrices using Redheffer’s star product, composite right-left-handed (CRLH) transmissions line theory, four-terminal network and boundary conditions in electromagnetics are applied to WIC simulation based on graphical user interface of MATLAB. The WIC simulation can be used for designing the CSRR based BPF circuit and illustrating the electromagnetic field in the circuitry layered structure. The results of WIC simulation and the traditional simulation agree well with the theoretical and measured results.

本文提出了结合散射矩阵方法和波迭代计算（WIC）的基于互补裂环谐振器（CSRR）的带通滤波器分析。WIC是用于分析微波和毫米波电路与系统的电磁问题的数值模型。基于MATLAB图形用户界面，利用Redheffer的星积，复合右手-左手（CRLH）传输线理论，四端网络和电磁学中的边界条件的散射矩阵被应用于WIC仿真。WIC仿真可用于设计基于CSRR的BPF电路，并说明电路分层结构中的电磁场。WIC仿真和传统仿真的结果与理论和测量结果吻合得很好。
