二维光子晶体弯折波导的计算程序，不过只有TM模，但TE模恨容易就能从中重写出来(Two-dimensional photonic crystal waveguide)

说明：  基于平面波展开 传输矩阵计算2维矩形光子晶体模型 计算可得出相关图谱 handbook中除了参数说明还有参考文献等(Plane wave expansion based on the transfer matrix calculation of 2-D model calculation of rectangular photonic crystal patterns can be drawn from the relevant handbook of parameters except that there are references such as)

Maximum Length PN sequences are binary sequence generators that are capable of outputting all possible combinations of binary sequences in 2^m-1 cyclic shifts, where m is the size of the LFSR (Linear Feedback Shift Registers ) used in generating such sequences. Terms like Psuedorandom binary sequences (PRBS) or psuedonoise sequences are also used to refer m-sequences.
