DOI: 10.1016/j.ijleo.2017.12.098

Abstract: Abstract Vector beams with spatially inhomogeneous polarization have been under researched for years, and a common analysis method is to decompose the vectorial field to two orthogonal circularly polarized components. While the former work concentrated… read more here.
