Metasurface holographic

Web15 feb. 2024 · Meta-hologram is a kind of novel hologram constructed using metasurface, which consists of a series of artificial optical antennas with subwavelength size. On the basis of photonic resonances, optical antenna has the ability to manipulate phase, amplitude and even polarization of the electromagnetic wave. Webmetasurface holograms are able to store and reconstruct full wave information of target objects. Therefore, they are used increasingly for 3D-displays, data storage, optical metrology and beam shaping applications [9]. However, most of the metasurface holograms are passive devices.
