Abstract :
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 Nf /P factor with Nf the number of unknowns in the reflector and P the number of MBFs, with respect to previous approaches.
