摺射率 介質 相對介電常數

Refractive Index ; medium ; relative permittivity
在通常情况下,我们熟悉的折射率公式n=sinθ1/sinθ2=√ε,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=√ε,进行修正.
在通常情況下,我們熟悉的摺射率公式n=sinθ1/sinθ2=√ε,是在一定條件下纔成立,噹光通過介質的電導率不為常數或介質有吸收時,此公式不再適用,應利用麥剋斯韋方程組及介質的邊界條件對摺射率公式n=sinθ1/sinθ2=√ε,進行脩正.

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.
