计算一维光子晶体透射率的程序, 可以手动输入任意序列, 程序只针对两种介质组成的序列.(One-dimensional photonic crystal transmission process, you can manually enter any sequence, the program only for sequences composed of two media.)

We propose a generalized equation to represent a continuum of surface reconstruction solutions of a given non-integrable gradient field. We show that common approaches such as Poisson solver and Frankot-Chellappa algorithm are special cases of this generalized equation.
