Aim To study the reflection and transmission on the interface of two uniaxial crystals. Methods For the intrinsic vibration in the two crystals, using the boundary conditions of electromagnetic field, the distribution of amplitudes for the lights of reflection and transmission are analyzed. Results The coefficients of reflection and transmission are given. Conclusion On the interface of two uniaxial crystals, for one incidenct beam, there exist two reflected beams and two transmitted beams. Based on the boundary conditions of electromagnetic field, the ratios of reflection and transmission can be calculated, and they have more complex expression than isotropic condition.
