Schematic of the designed vectorial hologram metasurface device. Different holograms in eight polarization channels can be generated when the circularly polarized THz wave impinges on the metasurface, because the phase and polarization of the transmitted THz wave can be individually modulated. The hologram in a channel can be hidden by choosing the corresponding detected polarization state.
