“…where, s1=(s 1x , s 1y ) and s2=(s 2x , s 2y ) are positions of two points in the received plane, k=2π/λ is the wave number with λ being the wavelength. The term 'exp[ψ * (s1, ρ1)+ψ(s2, ρ2)] m ' represents the second-order statistical average of complex phase disturbances caused by atmospheric turbulence, according to the Kolmogorov statistical theory of turbulence and the quadratic approximation of the Rytov phase structure function [20,21], it can be given by:…”

Based on the extended Huygens Fresnel principle and Rytov approximation, we have theoretically derived the analytical formula for the propagation of partially coherent electromagnetic hyperbolic-sine-Gaussian vortex beam (PCEShVB) in anisotropic atmospheric turbulence. And the evolution characteristics of average intensity, the degreed of coherent(DOC) and the degree of polarization(DOP) of the beam in turbulence have been studied in detail. The results show that in the propagation process, the intensity distribution of the beam will appear spiral structure distribution, and the overall distribution of the light spots will rotate, and the rotation direction is related to the sign of the topological charge. The DOC distribution of PCEShVB will show a pattern similar to beam interference fringes with the increase of propagation distance, and the number of ‘interference fringes’ is greatly affected by the hyperbolic sine parameter. In addition, PCEShVB with large initial coherent length and hyperbolic sine parameter will obtain a large DOP. Finally, we use the random phase screen method to verify the correctness of our theoretical results.

Using the extended Huygens–Fresnel principle and the Rytov approximation, the analytical formula for the propagation of a partially coherent electromagnetic hyperbolic-sine-Gaussian vortex beam (PCEShVB) in anisotropic atmospheric turbulence has been theoretically derived. Detailed studies have been conducted on the evolution characteristics of the average intensity, the degree of coherence (DOC), and the degree of polarization (DOP) of the beam in turbulence. The results show that during propagation, the intensity distribution of the beam will exhibit a spiral structure, and the overall distribution of the light spots will rotate in a direction related to the sign of the topological charge. The DOC distribution of PCEShVB will display a pattern reminiscent of beam interference fringes with an increase in propagation distance, with the number of “interference fringes” greatly impacted by the hyperbolic sine parameter. Furthermore, PCEShVB with a large initial coherent length and hyperbolic sine parameter will increase the degree of separation of the spots and yield a large DOP. Finally, for the validation of the theoretical findings, the random phase screen method was employed to simulate the propagation of PCEShVB through anisotropic atmospheric turbulence. The studies revealed a consistent alignment between the simulation results and the theoretical predictions.
