A block iterative algorithm is proposed to solve electromagnetic scatt
ering problems involving multi-object scatters. The problem is formula
ted using a hybrid method, which combines the generalized multipole te
chnique (GMT), and the method of moments (MoM). The proposed algorithm
shows a very fast convergence, mainly when the iteration is performed
in an adequate sequence. This sequence can be easily found using empi
rical rules based on geometrical considerations. Some results are pres
ented in order to show the efficiency and accuracy of the proposed met
hod.
