用matlab实现二维情况下TM波在自由空间的的传播仿真，带有PML边界.很直观的！(realize the propogation of electromagnetic in TM mode under 2-D situation in free space，with respect to the PML ABC.)

说明：  matlab数值积分工具箱自己加入到工具箱就能够使用了(matlab numerical integration toolbox itself can be added to the toolbox used)

matlab编程教程。从最基本的matlab知识介绍开始，最后涉及到程序设计(matlab programming tutorial. Introduced, and finally it comes to programming from the most basic Matlab knowledge)

　　非晶态硅Forouhi-Bloomer模型参数拟合计算 　　半导体材料对光的吸收作用用k表示。材料的k一般都会随着入射光的波长的改变而改变。其变化规律因材料而异，但是对于同一类型的材料常可以用一种模型来表示。但是对于特定的材料，其模型参数的确定常的通过曲线拟合的方法得到的。 　　题目： 　　对于非晶态的硅，其K满足如下模型： 　　 　　其中A、B、C为系数，且均大于零，并满足4C-B2>0 Eg为禁带宽度，值为1.3 ev , E为能量。 　　现已知一组E对应的K值，通过曲线拟合的方法求出A,B,C。(Curve fitting)

类似于心电图在显示屏上慢慢地绘制I love U，是理工男表白的绝佳工具。(Similar to the electrocardiogram slowly draw I love U in the display is the perfect tool Polytechnic male confession)
