e (extraordinary)_ray

The discussion on the extraordinary ray s total reflection;

非常光线的全反射临界角

The extraordinary ray neither obeys the refractive law,nor has certain index of refraction in nonisotropic medium.

非常光线在各向异性媒质中传播不遵从折射定律 ,亦无确定的折射率 。

of the extraordinary ray is derived at the interface between two anisotropic mediums by means of Fermat s principle.

应用费马原理推导出主截面内的非常光线通过两种各向异性媒质分界面时的反射定律和折射定律。

The propagating direction of e-rays in common optical devices-Wollaston s Priam and Nicol s Prism is deduced strictly from the general formulas of the propagating direction of extraordinary rays in single-axle crystals.

从非常光线在单轴晶体内部传播方向的一般公式出发，严格导出了常见的两种光学元件渥拉斯顿棱镜和尼科耳棱镜中e光的传播方向。
