The optical permittivity of the liquid crystal (LC) is periodic along x with a period of 0.2 μm and behaves as a diffraction grating for light polarised along the y axis. The value of the relative permittivity ε yy (non-dimensional) at t = 0 ms in a small central region of the simulated domain is illustrated (colour legend on the right). The isotropic refractive index of glass is also colour-coded with the same scale for comparison. The horizontal lines represent the boundaries of the LC.
