In this work, the propagation of vortex beams is treated using a catastrophe theory approach.
Analytic expressions are deduced to describe caustic surfaces produced by vortex lenses …

This paper is devoted to studying the Bessel beam propagation in cylindrical coordinates
using the Hankel transform beam propagation method (HT-BPM) and their behavior in …

In this paper, one kind of multi-focusing electric and magnetic field which is sourced from an
azimuthally polarized vortex circular hyperbolic umbilic beam (APVCHUB) is presented …

We have obtained an expression for the amplitude and intensity of the field along the caustic
line, which is formed during autofocusing when the generalized lens is illuminated. Two …

For autofocusing beams formed by a generalized lens, an expression is obtained for the
amplitude and intensity of the field along the caustic line. We have considered three types of …

Nondiffracting beams have the particular property that their time averaged intensity profile
does not change when it is measured in every plane normal to the direction of evolution of …

In this paper, the scattering of a Bessel beam by PEC and dielectric circular cylindrical
scatterers is analyzed and discussed. In particular, it is shown that the scattering by …

Structuring light is an essential key to control optical forces, transfer signals, or enhance the
capabilities of imaging systems [1, 2]. Micro-manipulation of particles as well as micro-and …
