摘要: A statistical approach is presented for calculation of the extinction light by small, irregularly shaped particles in framework strong-permittivity fluctuations theory. To this end Dyson equation bilocal approximation solved. The method, which applicable even with large optical constants, used determination cross section interstellar dust visible and infrared region. are assumed to be aggregates ballistic particle cluster aggregation type. strong enhancement far found. For moderate constants results agree Bruggeman’s effective-medium
