Electro-Optical Effects in Cholesteric Phase

  • Lev M. Blinov


A cholesteric forms a helical structure and its optical properties are characterised by the tensor of dielectric permittivity rotating in space. We are already familiar with the form of the cholesteric tensor (see Section 4.7). It was Oseen [1] who suggested the first quantitative model of the helical cholesteric phase as a periodic medium with local anisotropy and very specific optical properties. First we shall discuss more carefully the Bragg reflection from the so-called “cholesteric planes”.
