Transmittance and energy transfer of Gaussian beam propagation in anisotropic compressible turbulence

Abstract

Turbulence affects the transmittance of optical wave propagation. Reduced transmittance causes increased power loss in wireless communication systems. This phenomenon is even more pronounced in compressible turbulence, which generally occurs near supersonic or hypersonic aircraft. Compressible turbulence alters the level of power attenuation on optical wave propagation, reducing the performance of aircraft communication. In this paper, the wave structure function (WSF) and optical intensity of a Gaussian beam propagating in anisotropic compressible turbulence are deduced. The effect of anisotropic compressible turbulence on a Gaussian beam is investigated. The results show that the essential effect of turbulence on Gaussian beams is the dispersion of energy instead of attenuation. Anisotropic compressible turbulence improves the power efficiency of wireless communication systems. In addition, compressible turbulence effects on the transmittance of Gaussian beams are represented versus wavelengths and waist widths of the beams.
