Effect of monomer size for the aggregates with a porosity of ~59%. The orange and green lines are the results for R₀ = 200 nm (BAM2 clusters of 128 monomers) and 400 nm (BAM1 clusters of 16 monomers), respectively. The porosity of each aggregate is indicated in the legend. The inset panel shows the angular dependence of the degree of polarization (−S₁₂/S₁₁) at two wavelengths (solid lines: λ = 1.63 μm, dotted lines: λ = 1.04 μm).
