Controlling intensity and phase of terahertz radiation with an optically thin liquid crystal-loaded metamaterial

We experimentally demonstrate intensity and phase modulation of terahertz radiation using an actively controlled large-area planar metamaterial (metaﬁlm) hybridized with a 12lm thick layer of a liquid crystal. Active control was introduced through in-plane electrical switching of the liquid crystal,...
