MAGNETO-OPTICAL CRYSTAL THINGS TO KNOW BEFORE YOU BUY

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。For optical fibers along with other waveguides, it is much more ideal to consider the difference of efficient refractive indices. That is straight connected to the primary difference in imaginary values of the propagation constants.The bir
