An iterative MoM-PO method based on a MBF/Krylov approach

In this paper a fast iterative technique is presented for the analysis of large reflectors through the combination of the Method of Moments (MoM) with Physical Optics (PO). The iteration is based on a Krylov approach imposing orthogonality on each step, together with the use of Macro Basis Functions...

Description
Summary:In this paper a fast iterative technique is presented for the analysis of large reflectors through the combination of the Method of Moments (MoM) with Physical Optics (PO). The iteration is based on a Krylov approach imposing orthogonality on each step, together with the use of Macro Basis Functions (MBF) on the feed region. The complexity of the problem is reduced by a N f /P factor with N f the number of unknowns in the reflector and P the number of MBFs, with respect to previous approaches.
