    Efficient analysis of large finite arrays via mom formulation with dft based acceleration algorithms
    (2003) Çivi, Ö. A.; Ertürk, Vakur B.; Chou, H.-T.
    A DFT based acceleration algorithm is combined with iterative methods to accelerate the computation of Method of Moments (MoM) analysis of electromagnetic radiation/scattering from large, finite free-standing and printed elements of phased arrays. Computational complexity of this approach is O(Ntot), where Ntot is the number of unknowns. Numerical results are presented to validate the efficiency and accuracy of the method.
