Multi-functional metasurfaces have attracted considerable attention over the recent years. However, the passive multi-functional metasurface is subjected to fixed functionalities. In this work, we propose the design of a two-dimensional dynamic metasurface where the meta-atom is individually addressable by an elaborately designed bias system. Three different kinds of holographic imaging containing focusing spots, numbers, and letters are fulfilled at different working frequencies.
