摘要：
In this research, we investigated tight focusing of vector beams with negative orders. It is theoretically proven that the lengthwise component of the spin angular momentum is equal zero near the focal area only for the first order of the incident beam. It was shown using numerical simulations and Debye integrals that local subwavelength regions with circular and elliptic polarization of opposite signs are formed in front of and behind the focal plane.
