要約(英語): The non-radiative dielectric (NRD) waveguide, which has a structure with a dielectric line sandwiched between two metal plates, is known to have low loss and excellent non-radiative properties in the terahertz region. Nematic liquid crystals (NLCs) with good response and large dielectric anisotropy even in the terahertz wave region, have been attracting attention in recent years as one of the high-frequency materials. By replacing a part of the dielectric with a NLC, a NRD waveguide type terahertz variable phase shifter can be obtained. In this study, we use simulation to analyze the electric field distribution in the structure of the proposed NRD waveguide type phase shifter, and clarify the response characteristics with both simulation and experimental results. The response improvement of this device is also discussed.
