Abstract

Based on the ABCD transfer matrix and Collins formula, the analytical expressions of the complex amplitude of the Bessel–Gaussian beam in a chiral medium are derived. By introducing vector potential in the Lorentz gauge, the electromagnetic field components of the Bessel–Gaussian beam are determined under the paraxial approximation. Through numerical calculations, the propagation of the Bessel–Gaussian beam in a chiral medium is examined. Results show that Bessel–Gaussian beams split into the left circularly polarized beam and the right circularly polarized beam with different propagation trajectories. The propagation trajectory of the Bessel–Gaussian beam can be controlled by varying half-cone angles of the Bessel–Gaussian beam and the chiral parameter of the medium. The dynamical characteristics, including energy, momentum, spin, and orbital angular momentum, of Bessel–Gaussian beams in a chiral medium are also simulated and discussed in detail. The results will be helpful to understand the interaction mechanism between structured light beams and a chiral medium.
