Abstract
Propagation characteristics of a shear horizontal (SH) wave in a cell struc ture containing a nematic liquid crystal layer are described on the basis o f numerical analysis and experimental results. The SH wave propagation is d escribed by the numerical analysis result for the nematic liquid crystal as an anisotropic liquid. considering the director angle of the liquid crysta l. The temperature dependence of effective viscosities of a typical nematic liquid crystal N-(p-methoxybenzylidene)-p'butylaniline)] (MBBA) is evaluat ed from the measurement of the phase velocity change of the SH wave in the liquid crystal cell.
