Analyzing the study of propagation characteristics of a vortex beam in a chiral medium

The analysis of the propagation of a Lorentz-Gauss vortex beam (LGVB) in a chiral medium is of significant interest to researchers in the optical field. LGVBs are also called structured, shaped light beams since they have well-defined orbital angular momentum (OAM). The propagation problem is examined by expressing the LGVB fields in a chiral medium with the extended Huygens-Fresnel diffraction integral (HFDI) formula as well as the optical ABCD matrix system. To analyze the propagation dynamics, the effects of LGVB configuration factors, embracing the OAM mode index, propagation distance, chirality parameter, and beam waist radius, are thoroughly investigated. LGVB is simulated in the context of both beam characteristics and chiral factor. There are various intensity modes for generating the LGVB, which are controlled by observing the beam characteristics. According to the numerical results, the beam parameters and chiral parameter during beam propagation influence the optical characteristics of the LGVB within the chiral medium. This research will aid electromagnetic scattering, propagation, optical manipulation, sorting, and light-matter interaction analysis. Furthermore, the results of this study could help to understand how LGVB interacts with a chiral medium through various material structures.
