Complex equivalent index of symmetrical periods
In this paper, the equivalent index of symmetrical periods is extended to the complex-number fields, then the reflectance in the stop band is calculated with the aid of the formulas of complex function. The admittance locus is used to explain the reasonableness and completeness of the complex equivalent index. A diagram of reflectance vs. equivalent index is given, by which the reflectance in the stop band can be obtained easily.
