摘要：

We explore a radially polarized vortex beam with broken axial symmetry under tight focusing conditions. The beam's three mutually orthogonal polarization components (radial, azimuthal, and longitudinal) are all rotated by an angle of pi/2 with respect to the input field in the focal plane. We validate this effect experimentally. Finally, we prove that this effect can be used to transport nanoparticles. (C) 2017 Author(s).
