Photonic crystals are attractive optical materials for controlling and manipulating the flow of light. One dimensional photonic crystals are already in widespread use in the form of thin-film optics with applications ranging from low and high reflection coatings on lenses and mirrors to colour changing paints and inks. Higher dimensional photonic crystals are of great interest for both fundamental and applied research, and the two dimensional ones are beginning to find commercial applications. The first commercial products involving two-dimensionally periodic photonic crystals are already available in the form of photonic-crystal fibers, which use a microscale structure to confine light with radically different characteristics compared to conventional optical fiber for applications in nonlinear devices and guiding exotic wavelengths. The three-dimensional counterparts are still far from commercialization but may offer additional features such as optical nonlinearity require

optisystem13相干通信的例子，非常实用，已经验证过！(Optisystem13 coherent communication examples, very practical, has been verified!)

vbalst 的自己编写的迫零检测程序，包含有误差和无误差两种情形(vbalst' s own testing procedures prepared by zero-forcing, contains two kinds of errors and error-free case)

有AI比较控制的一个小程序， 用MATLAB的rule实现的AI比较。(AI car function. use MatLab to get the AI rules)

绘制控制系统近似bode图，为了做自动控制原理作业时偷点懒。虽然matlab自带bode函数但是作业要求画近似的。(Drawing control system approximation bode diagram, when you steal lazy to do the job of Automatic Control Theory. Although matlab function but the job comes bode asked to draw approximate.)

几个控制理论的小程序，可以方便学习自动控制理论这门课(Can easily end the camera to the image transmitted matlab program for the software called.)

一个利用matlab仿真实现CDMA的代码，欢迎大家参考：）(Realize the use of matlab simulation of a CDMA code, welcomed the U.S. reference:))
