N2 - A predicting methodology of scattering by a cluster of multi-objects/ systems is proposed in this paper. In this predicting methodology, a representation of scattering by each object/system in the cluster is formulated with plane waves. Then an equation based on this plane wave representation is established for formulating interaction among objects/systems in the cluster. Finally, the equation is efficiently solved with iterative solvers, and the scattering by the cluster is computed. The accuracy and efficiency of this predicting methodology are well validated by various numerical experiments. The numerical performance of the equation for the interaction is also studied in detail. It is shown that the equation established in this paper converges much faster than those in the fast multipole method (FMM). Since the plane wave representation for each object/system can be determined by either measurement or simulation, this predicting methodology can well integrate the measured data and simulation results together for predicting scattering by very complex clusters. Furthermore, since the plane wave representation of each object/system can be established as a database and reused in other clusters, this predicting methodology has high efficiency.
