Two dimensional Airy beam soliton [PDF]

open access: yesScientific Reports, 2022
We demonstrate the formation of a two dimensional Airy beam soliton in a photorefractive crystal. By simply varying the nonlinearity strength we identify several scenarios showing the coexistence between an Airy beam and the emerging soliton. The soliton

Plasmonic Metalens to Generate an Airy Beam [PDF]

open access: yesNanomaterials, 2023
Airy beams represent an important type of non-diffracting beams—they are the only non-diffracting wave in one dimension, and thus they can be produced with a cylindrical geometry that modifies a wavefront in one dimension.

Airy-beam tomographic microscopy. [PDF]

open access: yesOptica, 2020
We introduce Airy-beam tomographic microscopy (ATM) for high-resolution, volumetric, inertia-free imaging of biological specimens. The work exploits the highly adjustable Airy trajectories in the 3D space, transforming the conventional telecentric wide-field imaging scheme that requires sample or focal-plane scanning to acquire 3D information.

Multichannel Airy beam generator simultaneously for linear and circular polarized waves

open access: yesMaterials and Design, 2023
The Airy beam has intrigued long-held research interests and developed various striking applications attributed to the unprecedented diffraction-free, self-bending and self-healing properties. Metasurfaces with superior design freedom and small structure

Airy beam optical parametric oscillator. [PDF]

open access: yesSci Rep, 2016
AbstractAiry beam, a non-diffracting waveform, has peculiar properties of self-healing and self-acceleration. Due to such unique properties, the Airy beam finds many applications including curved plasma wave-guiding, micro-particle manipulation, optically mediated particle clearing, long distance communication and nonlinear frequency conversion ...

A physics-informed Airy beam learning framework for blockage avoidance in sub-terahertz wireless networks [PDF]

open access: yesNature Communications
The line-of-sight blockage is one of the main challenges in sub-terahertz wireless networks. Interestingly, the extended near-field range of sub-terahertz nodes gives rise to near-field wavefront shaping as a feasible remedy to tackle this issue ...

Beam Propagation Factor of a Cosh-Airy Beam

open access: yesApplied Sciences (Switzerland), 2019
Based on the second-order moments, the analytical expression of the beam propagation factor of a cosh-Airy beam has been derived. The beam propagation factor was determined by the decay factor and the cosh parameter.

Airy beams on incoherent background [PDF]

open access: yesOptics Letters, 2021
We present a class of diffraction-free partially coherent beams, each member of which comprises a finite-power, non-accelerating Airy bump residing on a statistically homogeneous, Gaussian-correlated background. We examine free-space propagation of soft apertured realizations of the proposed beams and show that their evolution is governed by two ...

Generation and regulation of two-dimensional autofocusing Airy beams based on holographic metasurfaces

open access: yesJournal of Information and Intelligence, 2023
This paper proposes a new method to generate a two-dimensional (2D) Airy beam and Airy autofocusing beam by using the scalar holographic metasurface with amplitude-phase modulation in the microwave band.

Propagation-invariant vortex Airy beam whose singular point follows its main lobe

open access: yesNew Journal of Physics, 2021
We propose and demonstrate a novel vortex Airy beam which is a superposition of an Airy beam and its laterally sheared beam with a π /2 phase shift.
