Abstract

A more accurate calculation is given of both the striped perturbation pattern and the square grid perturbation pattern that are formed in the planar cholesteric layer as soon as the applied field reaches a threshold value. Notably, it is shown that the distance between the boundaries must exceed a critical value in order to allow such a distortion. The values of the critical field and the wavelength of the distortion are compared with existing calculations
