采用Q张量法对光栅天顶向衍射器件进行了二维建模。示出的flexoelectrically驱动的两个基态之间的切换发生通过创建和湮灭的缺陷对，和的符号和幅度的电压阈值证明取决于光栅材料的相对介电常数。
A Q-tensor method is used to model a grating-aligned zenithally bistable nematic device in two dimensions. The flexoelectrically driven switching between the two ground states is shown to occur through the creation and annihilation of pairs of defects, and the sign and magnitude of the voltage thresholds demonstrated to depend on the relative dielectric permittivity of the grating material.
