PB39 Influence of absorption anisotropy in THz liquid crystal components

Abstract

THz electromagnetic wave has some unique properties such as penetration through various materials (paper, plastic, cloth etc.) and specific absorption band appears depending on materials (finger-print spectrum). There have been various studies for THz applications such as broadband communications, non-destructive testing and medical imaging. For the next phase of THz application, high quality of THz elements will be important. LC materials show relatively large refractive index anisotropy in THz region and they can have a potential application to some tunable devices. In this study, we investigate the new design scheme which includes the influence of absorption anisotropy in the THz LC components by using optically pumped submillimeter laser.
