WebMay 21, 2024 · Since the atmosphere has a strong scattering effect on ultraviolet light, the transmission of non-line-of-sight (NLOS) signals can be realized in the atmosphere. In previous articles, ultraviolet (UV) light atmospheric scattering has been characterized by many scattering models based on spot light sources with uniformly distributed light … WebMay 7, 2024 · Scattering losses exist in optical fibers because of microscopic variations in the material density and composition. As glass is composed of randomly connected network of molecules and several oxides (e.g. SiO 2, GeO 2 and P 2 O 5), these are the major cause of compositional structure fluctuation.Three different scattering processes may take place …
WebA new classical scattering phenomenon called ‘collective Rayleigh scattering’ (CRS) [2] has been predicted which involves the spontaneous formation of a particle density modulation on the scale of the radiation wavelength, thereby forming a refractive density grating. Radiation scattering from such an ensemble of particles is therefore ... WebApr 10, 2024 · Fig. 2.
