An algorithm that accelerates the iterative solution of boundary integral equations is presented. The matrices generated in the MoM discretization of the boundary integral equations exhibit special properties which are exploited in the proposed algorithm. The algorithm is motivated by the fact that the fields in an observation domain can be represented in terms of fields radiated by the reduced set of equivalent sources. The number of sources in the reduced set is directly related to the number of degrees of freedom of the field radiated by the original set in the direction of the observation domain. It also exhibits similarities with the multilevel algorithm proposed by Brandt.
