“…When an aircraft flies at speeds exceeding mach 5 in atmospheric environment, a highdensity plasma sheath will form around its surface due to intense friction with the surrounding air [1]. Until now, a rich assortment of investigations, encompassing both theoretical models and practical experiments, has demonstrated that plasma sheath turbulence(PST) features various sizes and shapes of turbulent vortices, exhibiting more robust turbulent characteristics than atmospheric turbulence [2,3]. Furthermore, it has been proved that the presence of PST can potentially disrupt communication between hypersonic objects and radar systems, making it difficult for lower frequencies airborne carrier signals to penetrate through it, and even resulting in communication link interruptions [4,5].…”

This paper establishes an evolution model for the spiral phase spectrum of a composite power Gaussian (CPG) vortex beam in plasma sheath turbulence (PST) based on the Rytov approximation theory and the modified von Karman spectrum. The impact of various parameters, including turbulence and beam attributes, on the spiral phase spectrum of the CPG vortex beam in PST is investigated through numerical simulations. Our numerical results reveal that the spiral phase spectrum of beam exhibits asymmetry which modulated by the structural parameter. Meanwhile, the resistance of the CPG vortex beam against turbulence strengthens as the wavelength increases and the topological charge decreases. The findings also demonstrate that the spiral phase spectrum of the CPG vortex beam incorporates a broader range of modes in isotropic PST compared to anisotropic PST. Furthermore, the impact of PST on the beam is intensified with a higher refractive index undulation variance and a smaller outer scale parameter.

“…e presence of anisotropic turbulent plasma sheaths around the vehicles can have a strong inuence on the communication characteristics between the vehicles and radars. It can perturb communication and in some circumstances may lead to a disconnection [7,8].In recent years, the propagation of various laser beams in anisotropic turbulent plasma has been investigated extensively [9][10][11][12][13].…”

The propagation properties of partially coherent circular flat-topped (FT) vortex hollow/nonvortex beams are studied in anisotropic turbulent plasma. The analytical expression of the optical intensity of these beams is obtained by employing the extended Huygens–Fresnel integral. The effects of the source and turbulent plasma parameters on the intensity distribution of partially coherent circular FT vortex hollow/nonvortex beams are analyzed numerically. The results show that partially coherent circular FT vortex hollow/nonvortex beams will finally converge into a Gaussian intensity profile at increasing propagation distances. The results also showed that the partially coherent FT vortex hollow/nonvortex beams with higher coherence are less affected by anisotropic turbulent plasma than the less coherent beams.

“…Li et al studied the refractive index spectrum of plasma sheath and bit error rate of the laser through plasma sheath based on fractal theory. [30,31] Zhang et al investigated the plasma channel's characteristics and performance. [32] In their work, the turbulent plasma sheath was treated as a fast fading wireless channel, and the simulation results showed that error floor took place for phase-shift keying and quadrature amplitude modulation, while frequency-shift keying with non-coherent detection was a promising way to mitigate the blackout problem.…”

The characteristics of light propagation through turbulent plasma sheath surrounding the hypersonic aircraft have been studied. The turbulent flow fields around a hypersonic aircraft are given by using the Navier–Stokes (NS) equations and k–ε turbulence model. Based on the distribution of flow field, refractive index and density of the plasma sheath for a blunt cone are discussed with different flight velocities and altitudes. The refractive index is mainly influenced by the electrons in the turbulent plasma sheath. The influence of different velocities and altitudes on the features of light propagation in the turbulent plasma sheath is analyzed. The results show that as the flight speed increases or the flight altitude decreases, the refractive index fluctuation becomes larger. It is also found that the refractive index fluctuation varies with the incident wavelength. This study shows how the characteristics of an optical beam propagating through plasma sheath are affected by the incident wavelength, flight velocities, and altitudes.
