Metasurface-Based Holographic Display With All-Dielectric Meta-Axilens
IEEE Photonics Journal, 2021 In a classical metasurface-based holographic display system, a clear holographic reconstruction image can be obtained only in the back-focal-plane of the lens. However, when the receiving plane deviates from the focal plane, the reconstructed holographic
