Abstract :
Propagation of a UV pulse in soot aerosols are studied using a two-frequency mutual coherence function. Soot aerosols are obtained by the diffusion-limited aggregation(DLA) model. Scattering characteristics of aggregate structures in soot aerosols are analyzed by GMM theory. The effects of different-positions of the aggregate on the scattering intensities, scattering cross section, extinction cross section, absorption cross section and asymmetry factor are computed and compared. The two-frequency mutual coherence functions of UV pulses in soot aerosols are simulated, and the effects of optical distance, frequency difference are analyzed.
