(a) Schematic of the unit cell design of the nanoslit antenna at rotation angle of θ. (b) Simulated geometric phase shifts for the transmitted converted spin component from the nanoslit antennas at different rotation angles of 0, 45°, 90°, 135°, and 180°. (c) Simulated electric field |E| distributions of nanoslit antenna under circular polarizations at 532 nm. (d) A SEM image of the fabricated homogeneous nanoslit antenna array. (e) Measured and simulated transmission spectra under circular polarization basis.
