用于提取CST中材料仿真结果的相对介电常数、相对磁导率、阻抗、以及综合参数-Relative dielectric constant, relative permeability, impedance, and comprehensive parameters, etc. of the material simulation results in CST

能够恢复出各个方向的电磁参数，比如果x y z方向的磁导率以及介电常数(Electromagnetic parameters that can be recovered in all directions)

用于仿真得到超材料的S参数后，利用S参数矩阵提取等效介电常数和磁导率(fter simulating the S-parameters of the metamaterial, the equivalent dielectric constant and permeability are extracted using the S-parameter matrix.)
