Angular and Orbital Angular Momenta in the Tight Focus of a Circularly Polarized Optical Vortex
Photonics, 2023 Based on the Richards-Wolf (RW) formalism, we obtain two different exact expressions for the angular momentum (AM) density of light in the focus of an optical vortex with a topological charge n and right circular polarization.

Longitudinal component of the Poynting vector of tightly focused cylindrical vector beam
Journal of Physics: Conference Series, 2018 We numerically investigated the tight focusing of cylindrical vector beam with wavelength of 532 nm by a diffractive lens with a numerical aperture 0.95. The simulation was carried out using the Richards-Wolf formulae.

Circular Polarization near the Tight Focus of Linearly Polarized Light
Photonics, 2022 We have considered the tight focusing of light with linear polarization. Using the Richards–Wolf formalism, it is shown that before and after the focal plane, there are regions in which the polarization is circular (elliptical).

On the radiative efficiencies, Eddington ratios, and duty cycles of luminous high-redshift quasars [PDF]
, 2010 We investigate the characteristic radiative efficiency \epsilon, Eddington ratio \lambda, and duty cycle P_0 of high-redshift active galactic nuclei (AGN), drawing on measurements of the AGN luminosity function at z=3-6 and, especially, on recent ...
