Abstract

Liquid crystal materials that demonstrate birefringence at terahertz frequencies present an opportunity for the development of adaptive terahertz optics. Liquid crystal devices often consist of several optical layers surrounding a thin liquid crystal film, which can make extraction of the material parameters challenging. Using broadband THz spectroscopy, we present a thin-film analysis of a liquid crystal device with a commercially available liquid crystal material (E7), up to 4 THz.
