Modeling Electrooptical Effects in Ferroelectric Liquid Crystals. 1. Basic Equations and Experimental Tests

摘要

Electrooptical effects in ferroelectric liquid crystal cells have been simulated and, the calculation results have been compared with experiments. Two sets of equations have been solved numerically: (1) the dynamic equations for the director coupled with the electric current equation; (2) the Maxwell equations which allow the calculations of the optical transmission T for different polarization, wavelength and coherency of light incident onto a cell The anisotropy of elastic, viscous and dielectric properties and arbitrary anchoring conditions have been taken into account. The experimental data on the director switching and the electroclinic effect in the Smectic C* phase agree quantitatively with the modeling, and novel features of these effects are discussed.
