Abstract
Due to the gradient of the phase shift as the wavelength in the reflection and transmission, the optical thin films coatings will present the spatial dispersion effect. The new kinds of super-prism thin film devices can be realized by well design interference effect inside of multilayer films to get the super-dispersion. The positive and negative spatial dispersion are existed in side of coatings, and is very sensitive to the angle of incident and wavelength. The analysis methods and the different kinds of spatial dispersion thin film filter devices and tunable spatial dispersion filter devices are presented in the paper.
