A method for studying the scattering properties of a cluster of dielectric spheres is proposed. The vector scattering problem is handled through Debye potentials and a mathematical technique that accounts for multiple scattering effects. The scattered field as well as the scattering and absorption cross sections can be computed without any restriction of principle on the angle of incidence of light and on the radia and refractive indexes of the spheres in the cluster. The resulting expressions take on the well known form when the cluster reduces to a single sphere.
