Fig. 5. Calculated normalized angular distribution of scattering intensity of four scattering samples with different particle diameters. The long dashed lines, dashed–dotted lines, and solid lines represent that the polarization of the incident light is vertical linear polarization (I1), parallel linear polarization (I2), and 45° linear polarization (or naturally polarized light, I1+I2/2), respectively.
