Abstract
A silicon based terahertz full wave liquid crystal phase shifter is provided. The liquid crystal phase shifter has a first silicon conductive substrate, a second silicon conductive substrate, a plurality of pads, and a liquid crystal. The first and second silicon conductive substrates, instead of the quartz glass and transparent electrode, such as ITO, are used as substrates and to provide electrodes of the liquid crystal phase shifter. Thus, the effect of the liquid crystal phase modulation of the liquid crystal phase shifter in the THz range can be improved.
