Accelerating polygon beam with peculiar features [PDF]

, 2018
We report on a novel kind of accelerating beams that follow parabolic paths in free space. In fact, this accelerating peculiar polygon beam (APPB) is induced by the spectral phase symmetrization of the regular polygon beam (RPB) with five intensity beam (

Symmetric Olver beams

Results in Physics, 2023
This paper presents an innovative form of the symmetric and autofocusing beam in theory and experiment. These symmetric Olver beams (SOBs) originate from the spectral symmetry phase of the Olver beams.

Pearcey plasmon: An autofocusing surface wave

Results in Physics, 2021
In this article, we present a new kind of autofocusing surface plasmonic wave: the Pearcey plasmon. The result shows that the Pearcey plasmon evolves at the silver-air interface in the form of two-dimensional Pearcey plasmon function.

Nonparaxial propagation and the radiation forces of the chirped annular Bessel Gaussian beams

Results in Physics, 2020
We propose a new class of abruptly autofocusing beams, the chirped annular Bessel Gaussian beams (CABGBs), which are based on the radial Bessel profile.
