This study introduces a multi-bit liquid crystal-based metasurface for programmable control of terahertz (THz) waves. The metasurface achieves a 3-bit working state and a substantial ∼270° phase shift around 0.28 THz. This high flexibility enables continuous steering of the THz single-beam pattern, allowing adjustment of beam number and beamwidth. This development contributes to advancing metasurface technologies in the THz regime.
