Bohmian Trajectories of Airy Packets [PDF]
, 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.

Airy-Gauss beams and their transformation by paraxial optical systems [PDF]
, 2007 We introduce the generalized Airy-Gauss (AiG) beams and analyze their propagation through optical systems described by ABCD matrices with complex elements in general. The transverse mathematical structure of the AiG beams is form-invariant under paraxial

Terahertz circular Airy vortex beams [PDF]
Scientific Reports, 2017 AbstractVortex beams have received considerable research interests both in optical and millimeter-wave domain since its potential to be utilized in the wireless communications and novel imaging systems. Many well-known optical beams have been demonstrated to carry orbital angular momentum (OAM), such as Laguerre-Gaussian beams and high-order Bessel ...

The Airy fibre: an optical fibre that guides light diffracted by a circular aperture [PDF]
, 2016 We have designed and made an optical fibre that guides an approximate Airy pattern as one of its guided modes. The fibre's attenuation was 11.0 dB/km at 1550 nm wavelength, the match between the fibre's mode and the ideal infinite Airy pattern was 93.7%,

Intensity-symmetric Airy beams
Journal of the Optical Society of America A, 2015 Theoretical, numerical, and experimental research on a novel family of Airy beams in rectangular coordinates having a symmetric transverse pattern of light intensity is presented. The intensity-symmetric Airy beams include both the symmetric Airy beam whose field amplitude is an even function of the transverse coordinates and the antisymmetric Airy ...

Results in Optics, 2023 Anisotropic Airy beams are presented as solutions to the parabolic wave equation. We obtain the cross polarization terms in the new beams using the elegant Mukunda–Simon–Sudarshan matrix substitution rule for transition from Helmholtz scalar wave optics to the Maxwell vector wave optics.

Transverse Spin Angular Momentum of Airy Beams
IEEE Photonics Journal, 2012 We show that a (1+1)D Airy beam can contain the density of spin angular momentum (SAM) normal to the direction of propagation if the polarization direction of its magnetic-field component is orthogonal to the transverse axis of the Airy profile. Although

2010 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

Generalised photon sieves: fine control of complex fields with simple pinhole arrays [PDF]
, 2015 Spatial shaping of light beams has led to numerous new applications in fields such as imaging, optical communication, and micromanipulation. However, structured radiation is less well explored beyond visible optics, where methods for shaping fields are ...
