用matlab所编的关于用传输矩阵法计算光子晶体的反射率,文件中将程序写在word文档中,并附带有在matlab下画的图,感觉很有用(using Matlab as in the use of the transfer matrix method photonic crystal reflectivity, Lieutenant General procedures documents written in word document, together with the painting under Matlab plans, feeling useful)

edem接触程序，用于计算各种模型的接触力(edem modle)

这是一个三次样条插值函数实现的C代码。如果插值点需要改变，可以在程序中改定。(This is a cubic spline interpolation function of the realization of the C code. If interpolation points need to change, the procedures will change.)

ABAQUS的二次开发，非常适合学习VDLOAD的同志们学习，来自廖公云老师的《ABAQUS有限元软件在道路工程中的应用》(Learning from Liao Gongyun teacher "ABAQUS finite element software ABAQUS secondary development, very for learning VDLOAD, comrades in road works")

改程序是计算出金属表面等离子体直波导的有效折射率随波长和传输长度随波的两色散曲线，另外给定Drude-Lorentzia模型参数给定后，还可以求解介电常数以及画出相应实部和虚部的曲线(This programer is used to calculate Ag relative dielectric constant accroding to the Drude-Lorentzia and sovle the transcendental equation for even illumination. At the same time,it can draw the diagram of relationship between the dispersion curve and the Transmission with the length. )
