| Abstract: | The analytic expressions of reflectivity and transmissivity at the front surface of a uniaxial crystal for a beam of incident monochromatic wave are given.The differences between electric field vector and displacement vector of E ray are discussed carefully so that Fresnel's equations and the expressions of reflectivity and transmissivity are modified.Numerical examples indicate that the modified expressions keep to the principle of conservation of energy. |

| Keywords: | uniaxial crystal birefringent reflectivity transmissivity |
