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