Effect of monomer size for aggregates with a porosity of ~87%. Upper panel: degree of linear polarization of light scattered by aggregates with the org composition at λ = 1.04 μm. The blue, orange, and green lines are the results for R₀ = 100, 200, 400 nm, respectively. Lower panel: wavelength dependence of the maximum polarization. The observed maximum polarization fractions are plotted as lower limits, since the amount of depolarization that the observed polarized light suffered is unknown.
