The actual angular dependency of the depolarization is difficult to model empirically for aggregates outside the RDG limit. For instance, a modest fit for depolarization calculated by our T-matrix data requires several polynomial terms. Instead, we use a simple empirical model for depolarization which is fairly good inside the tested range and produces valid values when extrapolating to several thousands of monomers. The empirical correction for the depolarization  \(depol\left(\theta\right)\), in Eq. (\ref{eq:P11} ) and Eq. (\ref{eq:P44}) is calculated as
