Circle airy beam
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… WebMar 10, 2024 · Ring-Airy beams have attracted increasing interest owing to its unusual ability to abruptly autofocus toward the focal point along a parabolic trajectory.

WebApr 10, 2024 · Airy beams are an intriguing type of non-diffraction wave packet that can exist in one-dimensional (1D) curved orbital plane systems. 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 … WebWe introduce a new class of (2+1) dimensional circle Pearcey beams (CPBs) with the abruptly autofocusing (AAF) characteristics.

WebFeb 1, 2024 · In summary, a kind of dual autofocusing CAB is proposed based upon the relation between autofocal position f and initial launch angle parameter v in this paper. By combining phases of two different initial launch angles (v 1 and v 2) into light fields of CAB, the beam would have two autofocal points; v 1 determines f 1, and v 2 determines a ... http://www.circlemairconditioning.com/
