Recognition of Orbital Angular Momentum of Vortex Beams Based on Convolutional Neural Network and Multi-Objective Classifier

Photonics, 2023
Vortex beams carry orbital angular momentum (OAM), and their inherent infinite dimensional eigenstates can enhance the ability for optical communication and information processing in the classical and quantum fields.

Microwave vortex beam launcher design [PDF]

IET Microwaves, Antennas & Propagation, 2018
A novel design for a vectorial vortex beam launcher in the microwave regime is devised. The beam is formed by launching a single guided transverse electric (TE) mode of a metallic circular waveguide into free‐space. Excitation is achieved by the mean of an inserted coaxial loop antenna.

Ionization of hydrogen by electron vortex beam [PDF]

Journal of Physics B: Atomic, Molecular and Optical Physics, 2019
Abstract Optical vortex beams have an extensive history in terms of both theory and experiment, but only recently have electron vortex beams been proposed and realized. The possible applications of these matter vortex waves are numerous, but a fundamental understanding of their interactions with atoms and molecules has not yet been ...
