Abstract: For conventional phase-gradient metasurfaces, the phase tuning is mostly fulfilled by the exploitation of a nanoantenna- or a Pancharatnam–Berry-phase-based nanoresonator. The former scheme typically suffers from a dispersive phase gradient, while the latter is dispersionless… read more here.
