The paper presents a method for independently controlling the phase of arbitrary orthogonal states of polarization (Pоля) using metasurfaces composed of linearly birefringent waveplate elements. This approach allows for the imposition of two independent and arbitrary phase profiles on any pair of orthogonal Polya, including linear, circular, and elliptical polarizations. The method combines the propagation phase, which can independently control linear polarizations, with the geometric phase, which can control circular polarizations. By varying both the dimensions and orientation of the metasurface elements, the authors demonstrate chiral holograms and elliptical polarization beamsplitters in the visible spectrum. This significantly expands the capabilities of metasurface polarization optics, enabling new applications such as polarization-switchable lenses and improved polarimeters.The paper presents a method for independently controlling the phase of arbitrary orthogonal states of polarization (Pоля) using metasurfaces composed of linearly birefringent waveplate elements.
