Two-dimensional (2D) materials offer unique opportunities for photodetection, light emission, energy harvesting, and enhanced light-matter interactions. Even more interest brings the artificially engineered 2D micro- and nanostructures with on-demand properties paving the way for a plethora of specific applications and devices including lensing, holography, imaging, polarimetry, biosensing, etc. The rapidly developing use of 2D nanostructures poses new challenges for their proper engineering and novel applications. This work focuses on the metasurfaces, which are two-dimensional periodic arrays of subwavelength scatterers. Despite their ultrathin thickness, metasurfaces efficiently manipulate light acting as the refractors, reflectors, absorbers, lenses, antennas, polarizers, etc. In this work, we develop new approaches and advanced algorithms for metasurfaces engineering and study their electromagnetic properties in both far- and near-field. The developed analytical and semi-analytical models are used to investigate the metasurfaces for the modification of the Brewster angle [1], the diffractionless in-plane transfer of the localized light [2], the development of planar polarizer [3], the enhanced light coupling and light-matter interactions.
