For particles grown in the two limiting cases of coagulation (ballistic particle-cluster agglomeration and ballistic cluster-cluster agglomeration), lower and upper limits of the extinction at wavelengths from 1 μm to 1 mm are derived. The particle sizes are in the Rayleigh limit and the number of constituent grains in each particle is constant. Effective medium theories, the discrete dipole approximation and the discrete multipole method are applied to compute the optical behaviour of the coagulated particles. The spectral representation for inhomogeneous media is employed to investigate topology effects systematically.
