Figure | The concept of the multi-dimensional multiplexing meta-hologram is enabled by the full-modulation metasurface. a, An illustrative example, for the hologram of 6 letters “ABHUST”, each letter has a unique polarization and propagating direction as an independent channel. b, Schematic illustration of the parallel tasking method. The supercell with 2×2 unitcells is used as the building block of metasurfaces and the rotating angle of each unitcell is divided into three sub-angles for parallel tasks.
