Search for new optical crystals by the chemical bond method.

Abstract: From the chemical bond viewpoint , dielectric properties of some practical materials with various crystal structures were
quantitatively studied. The correlation between constituent chemical bonds and dielectric properties of these crystals was analyzed
using the proposed chemical bond method. Furthermore , on the basis of the chemical bond method a combination method was
presented for the quantitative determination of dielectric properties of materials with a similar crystal structure. From the current
work , we may derive structural information concerning the nonlinearity origin of optical crystals , which is helpful for the nonlinear
optical crystal engineering. (Close Abstract <<<)
