An efficient solution of the generalized multipole technique (GMT) for large two-dimension scattering problems

In this work we propose a novel and efficient solution for the generalized multipolar technique (GMT). The solution is obtained throughout an iterative process, solving each multipolar origin separately, which avoids the inversion of the full impedance matrix. This implies a significant reduction of the computational and storage cost, enhancing the scope of application of the GMT method to larger problems.
