Spin Hall Effect of Double-Index Cylindrical Vector Beams in a Tight Focus [PDF]
Micromachines, 2023 We investigate the spin angular momentum (SAM) of double-index cylindrical vector beams in tight focus. Such a set of beams is a generalization of the conventional cylindrical vector beams since the polarization order is different for the different ...
