Phase Velocity evaluation of elastic wave propagating in nematic liquid crystal cell

摘要

Propagation characteristics of elastic waves in liquid crystal cell are described from the view points of numerical analysis. A periodical stripe domain pattern is induced by an interaction between the elastic wave and nematic liquid crystal and is observable via a polarized microscope. The propagation characteristics in the solid/liquid trilayer are related to the material constants. The oth mode is strongly dependent on the conditions of the liquid crystal layer, while the 1st mode is almost independent of the liquid phase condition.
