The recent trend in the miniaturization of everyday elements is also reflected in optics. The emerging field of so-called 2D flar optics is based on metasurfaces, which are surfaces composed of sub-wavelength scattering features, which bring new perspective to the known behaviour of light. Optical metasurfaces enable us to mimic the functionalities of traditional optical components but in only two dimensions., Petr Dvořák, Katarína Rovenská, Filip Ligmajer, Radim Chmelík, Tomáš Šikola., and V anglickém názvu je překlep metap surfaces - správně = metasurfaces
