Abstract

Abstract : Metasurfaces, two‐dimensional versions of metamaterials, retain the great capabilities of three‐dimensional counterparts in manipulating electromagnetic wave behaviors, while reducing the challenges in fabrication. By judiciously engineering parameters of individual building blocks (such as geometry, size, and material) and selecting specific design algorithms, metasurfaces are promising to replace conventional electromagnetic elements in nanoplasmonic/photonic devices. Significantly, such concept can be readily promoted to other disciplines, such as acoustics, thermal physics, and seismology. In this article, the latest advances in full control of electromagnetic waves with metasurfaces are briefly reviewed from a functionality perspective. A broad avenue towards real‐life applications of metamaterials has been opened up, although they are still at their infant stage. At the end, several promising approaches are suggested to extend the applications of metasurfaces. Abstract : Metasurfaces show a variety of novel phenomena and can be used in ultrathin devices. They are able to control several properties of electromagnetic waves such as amplitude, phase, and polarization. These excellent abilities of metasurfaces are widely employed in achromatic lenses, holograms, spin Hall effect, optical chirality discrimination, cloaking, etc. Ultrathin‐metasurface‐based strategies provide a promising avenue towards both scientific applications and potential daily‐life products.
