The MICE Muon Beam on ISIS and the beam-line instrumentation of the Muon Ionization Cooling Experiment [PDF]

open access: yes, 2012
The international Muon Ionization Cooling Experiment (MICE), which is under construction at the Rutherford Appleton Laboratory (RAL), will demonstrate the principle of ionization cooling as a technique for the reduction of the phase-space volume occupied

Tight focusing field of cylindrical vector beams based on cascaded low-refractive index metamaterials

open access: yesNanophotonics, 2023
Using low-refractive-index metamaterials, we design a transmission-type radial-angular cylindrical vector beam generator. A high numerical aperture lens is constructed using an asymmetric meta-grating structure. The metamaterial vector beam generator and

Vector polymorphic beam [PDF]

open access: yes, 2018
A scalar polymorphic beam is designed with independent control of its intensity and phase along a strongly focused laser curve of arbitrary shape. This kind of beam has been found crucial in the creation of freestyle laser traps able to confine and drive

The Propagation Characteristics of Circular Airy Beams with Propagational Fractional-Order Optical Vortices

open access: yesPhotonics
We investigate the propagation properties of circular Airy beams (CABs) with propagational fractional-order optical vortices (OVs). The superposition of the phase singularity and polarization singularity from a vortex vector beam (VVB) plays a ...

Joint Vector Sensor Beam Steering and Passive Time Reversal for Underwater Acoustic Communications

open access: yesIEEE Access, 2022
This paper investigates how to advantageously combine acoustic vector sensor field components for underwater communications. The joint vector sensor beam steering and passive time-reversal receiver structure is proposed and compared against beam steering

Propagation characteristics of radial phase-locked discrete vector beam generated from a Gaussian Schell-Model laser array in atmospheric turbulence

open access: yesResults in Physics, 2023
In this paper, combining the advantages of partial coherence, vector beam, and laser array in better resistance to atmospheric turbulence, high capacity, and high output power, we proposed a radial phase-locked discrete vector beam generated from a ...
