摘 要: 通过定义吸收性介质中光波矢量的等幅面单位矢量和等相面单位矢量,并分别应用相应的边界条件,获得了光在介质/吸收性介质、吸收性介质/介质界面的反射系数和透射系数。它们的值与入射角、介质的折射率、吸收性介质的复折射率有关。并且吸收性介质/介质界面的反射系数和透射系数还与吸收性介质中等幅面单位矢量和等相面单位矢量之间的夹角有关。此外,光通过介质/吸收性介质、吸收性介质/介质界面的反射系数和透射系数均可退化为介质/介质的特殊情况。
关 键 词: 光学;反射折射;复折射率;菲涅尔公式;光传输

Abstract: The planes of constant field amplitude and constant phase of light in the absorbing medium are defined by using the unit vectors. Using the corresponding boundary conditions, the reflection coefficient and transmission coefficient of the light through the interfaces of absorbing medium/medium and medium/absorbing medium have been obtained. The reflection coefficient and transmission coefficient are decided by the incident angle, the refractive index of medium and the complex refractive index of absorbing medium. The reflection coefficient and transmission coefficient of absorbing medium/medium are also related to the angle between the planes of constant amplitude and constant phase. Both the absorbing medium/medium and medium/absorbing medium can be simplified as medium/medium.
Key words: optics; reflection-refraction; complex refractive index; Fresnel formula; light propagation
