Three-Dimensional Hologram with Ultrathin Huygens’ Metasurface

Huygens
^'
metasurfaces, which can tailor both electric and magnetic dipole resonances, have been draw widespread concern. Here, a three-dimensional Huygens' metasurface holographic imaging with enhanced quality is designed whose thickness is only 0.033λ. The presented Huygens
^'
metasurface hologram may provide inspirations for the design of high-resolution imaging, ultrathin imaging device, security, and data storage.
