摘要
Complex wavefront engineering is realized through a random metasurface phase mask backed by a phase-only spatial light modulator. The metasurface consists of an array of subwavelength nanoscatterers which give the metasurface a pre-arranged disorder. Since the transmission matrix of the disordered metasurface is known, there is no need for extensive characterization measurements which are instead required in standard disordered optical devices.
