This work is a comparative analysis of the proposed mathematical model of the aggregate with the solution of the problem of light scattering obtained in the approximation of physical optics. A simplified mathematical model of the aggregate is proposed, based on the calculation of light scattering on each individual particle included in the aggregate, the results obtained for each particle are summed up, multiplied by the contribution coefficients to the total scattering. This approach allows you to build a solution tens of times faster, instead of the resource-consuming direct calculation of the problem of light scattering on the aggregate, while the error of such a simplified model is less than 20%.
