Tight Focusing of Vector Beams without Longitudinal Component of the Electric Field

In this work we investigated the focusing characteristics of vector beams with sector azimuthal polarization. The simulation was performed using the Richards-Wolf formulas. It was demonstrated that in a tight focus for these beams there is no longitudinal component of the electric field. Previously, a similar effect was demonstrated for azimuthally polarized light only. The longitudinal component of the spin angular momentum for these beams was calculated, and the possibility of creating sector azimuthally polarized beams (beams with V-line singularities) using vector waveplates was demonstrated.
