A REVIEW OF BIREFRINGENT CRYSTAL

各向异性透明晶体如方解石、石英等的折射率，是其固有的特性，称为永久双折射。If the electrical industry has the way of the optical axis, one particular obtains the amazing index ne. This is achievable provided that the propagation route (a lot more specifically, the path on the k vector) is perpendicular to the opt
