A new approach for the analysis of large radiation or scattering problems is presented. It is based on a compartmentalization of the objects into geometrical regions called windows. We generate a coupling matrix for each window using a CBFM-MLFMA combination. The different effects or interactions between windows consider excitation vectors due to the fields radiated by previously calculated currents. This approach is highly accurate and efficient in terms of memory and CPU time.
