Wave analysis of airy beams

open access: yes2010 URSI International Symposium on Electromagnetic Theory, 2010
The Airy beams are analyzed in order to provide a cogent physical explanation to their intriguing features which include weak diffraction, curved propagation trajectories in free-space, and self healing. The asymptotically exact analysis utilizes the method of uniform geometrical optics (UGO), and it is also verified via a uniform asymptotic evaluation

Higher-order moments and overlaps of Cartesian beams [PDF]

open access: yes, 2010
We introduce a closed-form expression for the overlap between two different Cartesian beams. In the course of obtaining this expression, we establish a linear relation between the overlap of circular beams with azimuthal symmetry and the overlap of ...

Dynamic Propagation of Quadratically Chirped Airy Beams in the Right-Handed and Left-Handed Material Slabs

open access: yesIEEE Photonics Journal, 2017
We analytically and numerically investigate the dynamic propagation of the quadratically chirped Airy beams in right-handed material (RHM) and left-handed material (LHM) slabs.

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.

Planar Airy beam light-sheet for two-photon microscopy [PDF]

open access: yes, 2020
We demonstrate the first planar Airy light-sheet microscope. Fluorescence light-sheet microscopy has become the method of choice to study large biological samples with cellular or sub-cellular resolution. The propagation-invariant Airy beam enables a ten-

Bohmian Trajectories of Airy Packets [PDF]

open access: yes, 2014
The discovery of Berry and Balazs in 1979 that the free-particle Schr\"odinger equation allows a non-dispersive and accelerating Airy-packet solution has taken the folklore of quantum mechanics by surprise.

Generation and characteristics of an Airy vortex beam from the anomalous vortex beam

open access: yesResults in Physics, 2022
Hybrid beams have evoked a long-running research upsurge due to its unique properties and extensive application. In this paper, we propose a novel method to generate a kind of hybrid Airy vortex beam (AiVB) with orbital angular momentum (OAM) by imposing

Dual accelerating Airy-Talbot recurrence effect

open access: yes, 2015
We demonstrate the dual accelerating Airy-Talbot recurrence effect, i.e., the self-imaging of accelerating optical beams, by propagating a superposition of Airy beams with successively changing transverse displacements.

Nonparaxial shape-preserving Airy beams with Bessel signature [PDF]

open access: yes, 2014
Spatially accelerating beams that are solutions to the Maxwell equations may propagate along incomplete circular trajectories, after which diffraction broadening takes over and the beams spread out.

Laser Coherent Combination With Circular Array of Airy Beams

open access: yesIEEE Photonics Journal
A high-efficiency laser coherent combination method based on the virtue of the self-transverse acceleration effect of Airy beams is proposed and demonstrated by converting an array of Gaussian beams into Airy beams array to reduce laser beams separation ...
