Study on polarization features of carbonaceous particles in atmosphere pollutants

摘要: The carbonaceous particles are the main source of light absorption in atmospheric aerosol. Different from case tissue-like turbid media, environments can be described as an inherent attribute on scatterers rather than interstitial propagation effect. In this paper, we simulated optical due to and analyzed influence various parameters their polarization properties, such imaginary part refractive index, size shape. Also compare these results with our previous research work effect ambient medium. For single scattering, scattering angular distribution implies potential distinguishing different structural parameters. other hand, for week suspension system, using backward Mueller matrix polar decomposition method, find out that additional enhance depolarization moreover produce more diattenuation linear retardance those anisotropic particles. subsequent experiments standard samples show a good agreement simulation results. paper further studies phase function numbers, which explain unique phenomena. We hope fundamental help investigate how identify characterize features hybrid system.
