a Top view of the structure design with the combination of \(S\) and \({S}^{m}\). b SEM image of the fabricated metasurface. c The full-view of the intensity distribution of the measured meta-hologram. A clear image is shown at 30° but no image at −30°. d–f Measured vectorial meta-hologram at 30° with distribution of d uniform encoded intensity, e spatially distributed azimuth (“Infinity”) and f ellipticity (“Tai Chi”) angles of the polarization in the far-field. The blue scale bar in d-f represents 1 cm.
