"full set of polarization states (left/ right-handed circularly polarized light, linearly polarized light in different orientations) switchable across multiple channels, integrated into single optical metasurface... reflective gold-silica-gold plasmonic metasurface with 6 randomly interleaved metasurface regions, each outputting/ collecting different polarization states at distinct reflection angles simultaneously... integrating nanoscale plates bearing different rotational angles enables simultaneous output... imaging, sensing, communication"
