| Abstract: | Based on fractional theory,by simulating the fractional aggregation particles,using the discrete-dipole approximation method(DDAM) and calculating optical characteristics of the single aggregation particle,the author gets the relationships between the scattering intensity of aggregation particles and the changing incident wavelength.Then the numerical results are compared with the results of Mie theory and T-matrix.The paper proposes the angular distribution of linear polarizability of aggregation particles... |
