Cholesteric liquid crystals,Selective reflection,Angular dependence
The bandwidth of a patterned cholesteric liquid crystal is analyzed using a geometric method in which the short and long wavelength edges of selective reflection are estimated by the average refractive index of the optical path. The estimated wavelength edges approximately agree with those obtained by the FDTD method.
