Scattering of aerosol by a high-order Bessel vortex beam for multimedia information transmission in atmosphere

Abstract

The essence of wireless communication and multimedia information transmission is the propagation of electromagnetic waves in the atmosphere. Within the framework of Generalized Lorenz Mie theory, and combining the vector wave theory with the generalized multi-spheres Mie theory, the analytical solution to the scattering of the high-order Bessel vortex beam (HOBVB) by aerosol aggregation in atmosphere is investigated. The angle distributions of the scattered field of soot, silicate and nitrate aerosol cluster particles illuminated by a HOBVB are numerically discussed. The examples are selected to illustrate the effects of aggregation configuration, mean value, particle number, topological charge and half-cone angle of the beam on the angle distribution of scattered field. It is noticed that the angle distribution of scattered field is sensitive to the configuration of the cluster for the multiple refraction and interactive scattering. The variation of the mean value of radius of the aerosol aggregation will result in different scattering characteristics and different transmission efficiency. The integration of the scattering algorithm and deep learning can be used in inversion of the shape and components of the aerosol clusters and in the improvement of transmission efficiency of multimedia information in atmosphere.
