Abstract
Specific features of the optical properties of cholesteric liquid crystals (CLCs) in an external static magnetic field have been studied theoretically taking into account the magneto-optical activity. The boundary-value problem of reflection from a half-space of a planar CLC and light transmission through a finite layer of a magnetoactive CLC at normal incidence have been considered. Specific features of evolution of reflection from a half-space at a change in the magneto-optical activity parameter have been investigated. Existence of the effect of magnetically induced transmission (MIT) in a CLC with real parameters is shown. Specific features of the resonant MIT lines at different values of local optical anisotropy of a CLC have been discussed.
期刊介绍：
Optics and Spectroscopy (Optika i spektroskopiya), founded in 1956, presents original and review papers in various fields of modern optics and spectroscopy in the entire wavelength range from radio waves to X-rays. Topics covered include problems of theoretical and experimental spectroscopy of atoms, molecules, and condensed state, lasers and the interaction of laser radiation with matter, physical and geometrical optics, holography, and physical principles of optical instrument making.
