Fractal-like aggregates are usually modeled as monodisperse particles positioned in point contact. However, in reality, much more advanced connections between primary particles exist. In this work, new parameters for measuring both the intersection level and the neck level were introduced. Then, the impact of the connection type on the spectral behavior of fractal-like WO3 aggregates was studied. For light scattering simulations, in the visible spectrum, the ADDA algorithm was used. The results prove that necks have strong impact on the spectral behavior of WO₃ aggregates and connections, which exist between primary particles, should not be excluded from models.
