折射率公式的修正

An Amendment of Refractive Index Formula

在通常情况下,我们熟悉的折射率公式n=(sinθ1)/(sinθ2)=(εr)^(1/2)是在一定条件下才成立,当光通过介质的电导率不为常数或介质有吸收时,此公式不再适用,应利用麦克斯韦方程组及介质的边界条件对折射率公式n=(sinθ1)/(sinθ2)=(εr)^(1/2)进行修正.

Under normal circumstances, the refractive index which we are familiar with, is a formula that would not set up except on certain conditions. And the formula would not be applicable when the conductivity of the medium which the light gets through is not a constant or the medium is absorbed. We should further deduce with Maxwell equations and boundary conditions of the media, then amend the refractive index formula.
