Abstract:
We have obtained explicit expressions for amplitudes of all components of the electric and magnetic vector of a family of vectorial nonparaxial linearly polarized vortex Hankel beams. Thus, closed-form analytical expressions have been derived for the projections of the Umov-Poynting vector and angular momentum vector. Up to now, projections of these vectors have been obtained only for the nonparaxial vectorial Bessel beams and paraxial vectorial Laguerre-Gaussian beams.

Keywords:
nonparaxial propagation, Hankel beam, optical vortex, vector electromagnetic theory, orbital angular momentum.
