中文摘要：
将提取样品相对介电常数和磁导率的电磁波问题转化为传输线和两端口网络问题，基于传输线和微波网络理论，导出了介质的相对本构参数与散射矩阵元素等参数的相互关系。电路和电磁仿真结果证明了本文所导出的样品相对介电常数和磁导率与反射系数、透射系数、工作频率和样品厚度关系的正确性。
英文摘要：
An equivalent transmission line and network with two ports eonstructed in the investigation of the electric circuit has been successfully applied to the problems of constitutive parameter retrieval for materials in electromagnetic fields and waves, and based on transmission-line and network theory, the relations between the scattering matrix and relative constitutive parameters of material are derived. The circuit and eleetromagretie simulation results presented show that the relation among relative permittivity, relative permeability and reflection coefficients, transmission coefficients, sample thickness is correct.
