A binary subwavelength four-zone transmission element with metasurface for simultaneously controlling the polarization and phase of laser light was synthesized and characterized. The element was manufactured in a silicon film spattered on a glass substrate. It performs the near-field conversion of a linearly polarized incident laser beam into a near azimuthally polarized beam with a phase shift of $\pi$ at diametrically opposite points of the beam. In the far field, the converted beam produces an intensity maximum at the center, as opposed to the minimum from the azimuthally polarized beam.
