- Abstract
2 Multifunctionality from the pattern design Polarization [[65]], [[66]], [[67]], [[68]], [[69]], wavelength [[20], [24], [69]], [[70]], [[71]], and angle [[72]], [[73]], [[74]], [[75]] of incidence are part of a non-exhaustive list of parameters of a given light source that are usually taken advantage of as multiplexing channels for the multifunctional metasurfaces [[21]], which realize holography, structural color, and beam steering at the same time.

Although only the function of holography can be tuned, the vectorial holography that relies on polarization of incident light will bring more information channels, which is vital for optical encryption. Matrix Fourier optics enables polarization multiplexing in holograms [[77]].
