Liquid crystal metasurface design. a Schematics of the liquid crystal metasurface. The grating period P = 950 nm, bar width W = 160 nm, and bar height H1 = 500 nm. The thickness of the liquid crystal layer H2 = 2.5 μm. b,c Simulated reflectance of the metasurface as a function of the liquid crystal rotation angle θLC for incident light polarized along the x-axis (b) and y-axis (c), respectively. d,e Simulated reflection phase of the metasurface as a function of the liquid crystal rotation angle θLC for incident light polarized along the x-axis (d) and y-axis (e), respectively. f Simulated z-component electric field distribution for incident light polarized along the x-axis at the wavelength of 1452 nm with θLC = 0°, corresponding to the black star in panel (b). g Simulated z-component magnetic field distribution for incident light polarized along the y-axis at the wavelength of 1479 nm with θLC = 45°, corresponding to the black triangle in panel (c)
