These beams have gained significant attention due to their unique properties, including non-diffraction, self-healing, and self-bending. In this study, we propose a method for generating high-efficiency and …
The term "Airy beam" derives from the Airy integral, developed in the 1830s by Sir George Biddell Airy to explain optical caustics such as those appearing in a rainbow. The Airy waveform was first theorized in 1979 by M. V. Berry and Nándor L. Balázs. They demonstrated a nonspreading Airy wave packet solution to the Schrödinger equation. In 2007 researchers from the University of Central Florida (United States) were able to create an… Websatisfying Maxwell's equations) is the beam we present here, and that the Airy beam found in [1] is simply the outcome of the paraxial approximation. We find the solutions for both TE and TM, where the beams exhibit shape-preserving bending with sub-wavelength features, and the Poynting vector of their main lobe displays a turn of more than 90 °.
