Tunable circular dichroism in all-dielectric metasurface with efficient wavefront manipulation

In this paper, an all-dielectric metasurface based on phase-change material Ge2Sb2Se4Te1 (GSST) working in the mid-infrared band is designed, and combined with Pancharatnam-Berry (PB) phase to realize multifunctional metasurfaces. The metasurface can convert incident circularly polarized waves to tr...
