TL;DR: In this paper, high-birefringence nematic liquid crystals were examined for selected physical properties, including rotational viscosity, splay, twist and bend elastic constants, ordinary and extraordinary refractive indices for light wavelengths in the range from 0.3 μm to 1.6 μm.

TL;DR: In this paper, the value of the birefringence (Δn) has been calculated by the transmitted intensity method at a 632.8-nm wavelength in three different nematic liquid crystals (2020, 1823A and 1550C) in different concentration.
Journal ArticleDOI
Polymer stabilized liquid crystal phase shifter for terahertz waves
TL;DR: An electrically tunable phase shifter for terahertz frequencies based on a polymer stabilized liquid crystal which allows for a simple device geometry and significantly reduced response times is proposed.
