Here the pore size distribution was separated by pore diameter into 10 nm bins ranging from 30 nm to 640 nm and the normalizing factor in the weighted sum was the number of pores in each bin, Np, divided by the total number of pores, Nt, in the pore size distribution. See Figures S15d and S16b for results of polydisperse calculations. Figure compares the results of monodisperse and polydisperse calculations at the same porosity. The contour plots in Figure (main text) and Figure were calculated using the monodisperse method (i.e., Eq S3). Finally, it is worth noting that complete modeling of light scattering from porous media requires consideration of multiple scattering, inter-pore spacing (e.g., how pores are distributed the material) and pore shape/orientation. However, the relatively simple modelling employed here provides clear insights into the interplay of dp, P, and pore size distribution.
