简介:
Metamaterials are artificially engineered materials whose optical properties arise primarily from their micro-structure ("meta-atom") and their macroscopic order. Metasurface, as a new emerging field of metamaterials, has aroused considerable interest due to their capability of arbitrary manipulation of the phase and amplitude profile at the interface. In this talk, we briefly summarize our latest experimental results on employing metasurfaces to control electromagnetic waves. Specifically, we will show how to realize a photonic spin-Hall effect with nearly 100% efficiency, how to achieve a surface-plasmon coupler that can excite surface plasmon polaritons (SPPs) very efficiently, and how to actively control the phases of electromagnetic waves with graphene-based metasurfaces
