"The phase functions can be fit by modifications of Mie phase functions for equal-volume spheres in a systematic way as outlined in Appendix A. Similar extrapolations can be made for the scattering and absorption cross-sections and the degree of linear polarization up to large values of N. "
Our model does not fit the phase functions by systematically modifying mie phase functions for equal volume sphere. Rather it fits phase functions by systematically modifying the coherent superposition of the scattering of the spherical monomers of the aggregate particle. I need to think about it! What I say is definitely correct for absorption cross section, but how about the phase function?
For polarization, it is systematically correcting monomer polarization.
