Metasurfaces are two-dimensional counterparts of metamaterials, which are artificial materials that possess unusual characteristics. With a variety of fascinatingly innovative and diverse uses, these specially-prepared surfaces with engineered patterns can modify the propagation of electromagnetic waves across the entire spectrum of wavelengths.
