This paper delves into the transmission dynamics of Bessel-Gaussian (BG) beams in three distinct dusty environments, leveraging the Generalized Lorenz-Mie Theory (GLMT) alongside a single scattering model for a comprehensive analysis. Through numerical simulations, the study explores the interaction between dust particle scattering and the attenuation and transmittance behaviors of BG beams, elucidating the influences of varying particle concentrations and visibility conditions typical of floating dust, blowing sand, and sandstorms. The findings reveal numerous determinants, including particle number concentration, optical visibility, wavelength, orbital angular momentum (OAM) modes, waist radius, cone angle, and polarization states, which significantly affect the transmission performance of BG beams in dusty conditions. Notably, the attenuation rate decreases with increasing wavelengths and higher OAM modes, thereby extending effective transmission distances. Furthermore, the strategic use of linear polarization emerges as an optimal approach for enhancing BG beam transmission efficiency in dust-rich environments. These insights are crucial for optimizing BG beam transmission in real-world applications, marking a significant advancement in the field.

多尘环境下 Bessel-Gaussian 光束的传输衰减研究


本文利用广义 Lorenz-Mie 理论 （GLMT） 和单个散射模型，深入研究了贝塞尔-高斯 （BG） 光束在三种不同的尘埃环境中的传输动力学。通过数值模拟，该研究探讨了尘埃粒子散射与 BG 光束的衰减和透射行为之间的相互作用，阐明了不同粒子浓度和浮尘、吹沙和沙尘暴典型能见度条件的影响。研究结果揭示了许多决定因素，包括粒子数浓度、光学能见度、波长、轨道角动量 （OAM） 模式、束腰半径、锥角和偏振态，这些因素会显着影响 BG 光束在多尘条件下的传输性能。值得注意的是，衰减率随着波长的增加和更高的 OAM 模式而降低，从而延长了有效传输距离。此外，战略性地使用线性极化成为在多尘环境中提高 BG 光束传输效率的最佳方法。这些见解对于在实际应用中优化 BG 光束传输至关重要，标志着该领域的重大进步。
