摘要
本文从几何光学和麦克斯韦方程组两种方法分析了e光波线和波法线重合的条件,首先从几何光学e光波的波法线波线的方向表达式,论述在何种情况下e光波线和波法线重合,并给出定量结果,同时从克斯韦方程组出发,较为详细的论证单轴晶体中e光的波线和波法线间的关系,通过比较,两种得出结果一致。通过分析可知当光轴与入射面垂直或相交的时候,e光波线和波法线重合。
The article aim for the ware normal and the light way of E ware. On the basis of the boundary condition of the electromegnetic ware and direction of ware normal and the light way takes place in the Nicol prisn, At the same time, the article from the condition under which they coincide discuss, and the quantative result is presented. From Maxwell equation set departure, demonstate the nexus of the ware normal and the light way of E ware takes place in the uniaxial crystal, it is the same conclusion.
