Nowadays liquid crystal materials have attracted considerable attention for realizing these electrically controllable microwave and milliwave components because they have a large dielectric anisotropy in the microwave and milliwave region. But liquid-crystal-loaded microwave and milliwave devices have one serious problem, that is, the response time when the driving voltage is removed, is very long as the order of 10 s, because the thickness of their liquid crystal layer is typically more than 50 μm. In this study, we discuss about using polymer stabilized nematic liquid crystals for improving the response time.
