WebThese metasurfaces combine propagation phase and PB phase, and encode complex amplitude information into these two channels. As functional demonstrations, we design two metasurfaces: (1) a switchable power-controllable axial bifocal metalens; (2) a switchable power-controllable horizontal/vertical bifocal metalens. WebThe proposed metasurface is easy to fabricate and the multipole response can be easily tuned through the dimension change. In this work, we engineer multipole response in the multipolar plasmonic metasurface and demonstrate a metasurface that can simultaneously support AR and AT in the visible and IR ranges.
