This PhD thesis has the ambition to develop large-diameter metasurfaces with high resolution and performance operating in the visible light range. A metasurface is made of subwavelength metallic or dielectric nanostructures whose shape and arrangement enables light to be focused and/or filtered. The interaction with light is due either to plasmonic resonances (metallic nanostructures) or cavity resonators (dielectric nanorods). By controlling this interaction through the judicious design of the metasurface elements, it is possible to locally control the phase and amplitude of the light traveling through the metasurface and arbitrarily control the wavefront […]
