Sub-Second Switching Speed Polarization-Independent 2 pi Terahertz Phase Shifter

Sub-Second Switching Speed Polarization-Independent 2 pi Terahertz Phase Shifter

This study develops a 2 pi terahertz (THz) phase shifter that stacks three layers of cholesteric liquid crystal (CLC) cells. Each CLC cell in the focal conic state with randomly helical structures exhibits isotropic properties for a THz wave and enables polarization independence. An external vertica...
