Abstract
An overview of the current developments and prospects for the use of metasurfaces in optics, particularly holography, is presented. Particular attention is paid to the physics of controlling the phase delay of radiation scattered by metaatoms and the transformation of an incident wave front by a metasurface. A number of examples demonstrate the effectiveness of focusing radiation and forming a holographic image by metasurfaces of various types.
