The refraction of rays in the Savart polariscope is different from the isotropic medium. We have analysed and discussed the refraction of rays in the Savart polariscope on the basis of the Snell law. The refraction formulae of the extraordinary rays and ordinary rays were derived. Results obtained may provide theoretical and practical guide lines for studying, developing and engineering of polarization interference imaging spectrometer.

The static large field of the view polarization interference imaging spectrometer is based on the modified Savart polariscope. There appears a dispersion between the ordinary ray and extraordinary ray when light passes through the modified Savart polariscope. The dispersion greatly influences the intensities and the results of the interferogram and target image in the static large field of the view polarization interference imaging spectrometer. At the same time, the incident angle determines the dispersion. When the light goes through the modified Savart polariscope, the dispersion occurs in the left plate, the half-wave plate and the right plate of the modified Savart polariscope. Using the extension of Snell's law, the dispersion in the crystal is theoretically calculated and numerically simulated separately. The relationship curve between incident angle and the dispersion is obtained by simulation.

By now, the negative refraction phenomenon occurs only in the microwave band in the left-handed materials, and this frequency band is called resonant frequency band. The application of the left-handed materials is greatly limited because the resonant frequency is low, and the source of wave is usually sun light or visible light.How to shift the resonant frequency from low frequency to high frequency, even to the visible light band, is an important and urgent research problem. Many parameters of the periodic structures will greatly affect the resonant frequency, including the shapes and sizes. The resonant frequency is shifted by adjusting the cell size.The relation that the resonant frequency band can be shifted and broadened from low frequency to high frequency with the reducing cell size, is obtained by simulation and experiment.
