Abstract

Metamaterials and metasurfaces are artificial structures whose optical properties go beyond the natural behaviour of light. Their appeal revolves around the possibility to design the optical response by changing the geometry of the structure using essentially the same material constituents [1]. Some classes of metamaterials and metasurfaces can be fabricated over macroscopic areas and have strong promise in a wide variety of applications, from planar lenses, efficient polarizers to nonlinear optics providing enhanced interaction between light and matter [2, 3, 4].
