    Abstract

    In this paper, a radially polarized Bessel lens based on a dielectric metasurface is proposed. It can efficiently convert linearly polarized light into radially polarized light and simultaneously achieve non-diffracting Bessel beams. Under the incidence of linearly polarized light, the left and right handed components of linearly polarized light are independently regulated by the asymmetric photon spin-orbit interaction. Finally, polarization conversion and wavefront control are simultaneously achieved by spin recombination. At wavelength of 532 nm, the numerical aperture NA=0.9, and the metalenses achieve a focus focal spot beyond the diffraction limit. The study has potential applications in particle acceleration and super-resolution imaging.
