Dane z Informatora o publikowanych wynikach prac naukowo-badawczych w 2001 roku Wydziału Elektroniki. The method of calculation of refractive indices for complicated crystals in the frame of "oriented gas" model are proposed and made on the basis of known magnitudes of anisotropic polarizability of chemical bonds between atoms. Principal refractive indices and optical indicatrix orientations of DGN crystal in para-and ferroelectric phases calculated in the frame of "oriented gas" model and experimentally observed have found to be close to one another.
