二维fdtd，mur吸收边界，方柱的散射(2D fdtd, mur absorption borders, side-scattering)

根据条形光波导折射率数据，分别针对宽高比a:b为1:1与 2:1两种情形，设计分析 ： 1. 满足单模与双模传输的 波导尺寸范围。（需要 给出色散曲线） 2. 针对两种情形，选取你 认为最佳的波导尺寸， 计算对应的模折射率。 （计算时假设上、下包 层均很厚）(According to the refractive index of the optical waveguide stripe of data, respectively, for an aspect ratio of a: b is 1: 1 and 2: 1 both cases, the design and analysis: 1. Meet single-mode and dual-mode transmission Bird size range. (need Given dispersion curve) 2. For both cases, you select That the best of the waveguide dimensions, Computes the corresponding mode refractive index. (Calculations assume that when the upper and lower package Layers are very thick))

精通matlab7是国外权威所写的matlab参考书，涉及到了国内书籍很少提到的一些问题，值得一看。(The proficient matlab7 foreign authoritative written matlab reference book, it comes to the domestic books rarely mention some issues, worth a visit.)

用割平面法求解整数规划。先不考虑整数约束条件，求松弛问题的最优解，如果获得整数最优解，即为所求，运算停止．如果所得到最优解不满足整数约束条件，则在此非整数解的基础上增加新的约束条件重新求解．(By cutting plane method for solving integer programming. Not considered integer constraints, the optimal solution relaxation problem, if the integer obtained optimal solution is sought, and operation stops. If the optimal solution does not satisfy the integer constraints, then on the basis of this non-integer solutions adding new constraints on the re-solving.)
