摘　　要：Quasicrystal has attracted lots of attention since its discovery because of the mathematically non-periodic arrangement and physically unique diffraction patterns.By combining the quasi-periodic features of quasicrystal and the special rotational symmetry with metasurface,many novel phenomena and applications are proposed such as optical spin-Hall effect,non-linear far-field radiation control,and broadband polarization conversion.However,the additional functions and effects brought by phase and amplitude modulation on quasicrystal arrangement still lack research.Here,we design and fabricate a dielectric quasicrystal metasurface which can simultaneously reconstruct holographic images and exhibit diffraction patterns by assembling the nanostructures in a quasi-periodic array.Most importantly,we combine the global arrangement of metasurfaces with the local responses(phase and amplitude)of meta-atoms for achieving the dual functionality.Furthermore,we also suppress the zero diffraction order in the far-field based on the quasi-momentum matching rule.The proposed method has great mathematical importance and explores new possibilities for multifunctional meta-devices for holographic display,optical switching and anti-counterfeiting.
