Sumario:A technique for the reduction of the CPU-time in the solution of complex electromagnetic problems using the characteristic basis function method is presented. This approach allows the analysis of electrically large cases iteratively using the multilevel fast multipole method to account for the matrix-vector products. It defines a new procedure for the fast computation of the characteristic basis functions and the reduced matrix. Some representative test cases show that the approach provides accurate results for complex bodies with a noticeable efficiency improvement.
