Abstract
We analysed the response of a tunable liquid crystal metamaterial (MTM) transducer in the terahertz frequency range. The MTM structure is based on the rod double-split square resonators (SSR) with back-to-back orientation. A full-wave analysis technique based on the finite-difference time-domain method (FDTD) was performed using QuickWave 3D electromagnetic solver. Terahertz transmission properties of the MTM structure can be controlled by the director of the liquid crystal layer. The main aim of this work is to determine the impact of the size of the SSR of the MTM transducer on scattering parameters of the analysed MTM transducer at terahertz frequency range. Numerical simulations were performed in the range 0.32–0.44 THz.
