Rayleigh light scattering on the director static inhomogeneities in filled flexoelectric nematic crystal
Director equilibrium configurations are obtained in the neighborhood of spherical and cylindrical impure particles in flexoelectric nematic liquid crystal under external electric field. Weak homeotropic and circular director anchoring with particle surface has been considered. Expressions obtained f...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Director equilibrium configurations are obtained in the neighborhood of spherical and cylindrical impure particles in flexoelectric nematic liquid crystal under external electric field. Weak homeotropic and circular director anchoring with particle surface has been considered. Expressions obtained for the director are used for numerical calculations of the angle distribution of the light scattering cross-section on the director structure inhomogeneities in the Rayleigh-Gan's approximation. All possible kinds of the light scattering are considered and dependence of cross-section on value of flexopolarization, external field and kind of the director anchoring is studied. In particular, it is shown that scattering cross-section essentially changes in the presence of flexopolarization. |
