3A15 Liquid Crystal Waveguide with a Periodic Structure in the Millimeter-Wave Region

Abstract

The planar waveguide with a periodic structure, which is composed of a nematic liquid crystal (LC) and dielectric materials, is proposed as the electrically controlled millimeter-wave devices. The millimeter-wave transmission properties of the LC waveguide are measured at 50GHz band and calculated using the finite-difference time-domain (FDTD) method. The influence of the applied voltage on the transmission properties is discussed.
