WebIn this paper, we simulate the focusing of a cylindrical vector beam (CVB) of second order, using the Richards–Wolf formula. Many papers have been published on focusing CVB, but they did not report on forming of the toroidal vortices of energy (TVE) near the focus. TVE are fluxes of light energy in longitudinal planes along closed paths around some critical … Web1.Introduction. Vortex beam is a special light field with a hollow dark core and spiral phase structure. The angular phase factor exp (i l ϕ) in the expression of the vortex beam represents the spiral phase structure, where l and ϕ represents the vortex beam's topological charge and azimuth angle, respectively. At the same time, each photon …
