An electromagnetic wavefront can be flexibly manipulated by discretephase coding on the coding unit. In this paper, we designed two codingmetasurfaces with 1-bit and 3-bit based on active tuning of Diracsemimetals by controlling the Fermi level (${E_F}$) with an external polarizationvoltage. The size and structure of the metasurface remain unchangedwith this strategy. Both designs were found to be dynamically tunable.
