Phase function of prolate spheroidic mono-disperse aerosol particles

Typical particles such as ice crystal, dust and black carbon are selected. to study the changing tendency of scattering phase function with prolate spheroidic mono-disperse aerosol particles with different aspect ratio, size parameter and refractive index by T-matrix. When the imaginary part of refractive index is neglected, for ice crystal with aspect ratio of 0.4 and spherical particle with the same surface area, their phase function ratio, ρ, is divided into five regions: 1) ρ≈1, the region of nearly direct forward scattering, 2) ρ>1, from about 5 to 30, 3) ρ
