数字水印matlab程序，只是简单的svd跟最简单的置乱方法Arnold的应用。没有用到小波算法。上传的dwt_svd_GUI.rar是完整的数字水印算法，用的是混沌加密。(Matlab digital watermarking process, with the svd simply the easiest way to Arnold scrambling applications. Wavelet algorithm is not used. From the dwt_svd_GUI.rar is a complete digital watermarking algorithm, using a chaotic encryption.)

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
