Super-reflector enabled by non-interleaved spin-momentum-multiplexed metasurface
A super-reflector was reported to enable on-demand control of both retroreflections and reflections of circularly polarized wave. Specifically, it performs four-channel abnormal reflections at each incidence of three multiplexed spatial frequencies.
