Journal ArticleDOI
Alternative formulation for invariant optical fields: Mathieu beams
TL;DR: A class of invariant optical fields that may have a highly localized distribution along one of the transverse directions and a sharply peaked quasi-periodic structure along the other and are described by the radial and angular Mathieu functions is presented.
Journal ArticleDOI
Unveiling a Truncated Optical Lattice Associated with a Triangular Aperture Using Light's Orbital Angular Momentum
TL;DR: It is shown that the orbital angular momentum can be used to unveil lattice properties hidden in diffraction patterns of a simple triangular aperture, and this effect can beused to measure the topological charge of light beams.
Journal ArticleDOI

TL;DR: In this paper, the orbital angular momentum density of Bessel beams is calculated explicitly within a rigorous vectorial treatment, which allows us to investigate some aspects that have not been analysed previously, such as the angular momentum content of azimuthally and radially polarized beams.
Journal ArticleDOI
Parabolic nondiffracting optical wave fields
TL;DR: The existence of parabolic beams that constitute the last member of the family of fundamental nondiffracting wave fields and their associated angular spectrum is demonstrated and their eigenvalue spectrum is continuous.
Journal ArticleDOI
Mathieu functions, a visual approach
TL;DR: In this article, the behavior of the Mathieu functions is illustrated by using a variety of plots with representative examples taken from mechanics, and they show how they can be applied to describe standing, traveling, and rotating waves in physical systems.
