    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.

    A new method for the prognosis of scan blindness angle in finite phased arrays of printed dipoles
    (IEEE, 2011) Avser, Bilgehan; Erturk, Vakur B.
    Scan blindness phenomenon is studied for finite phased arrays of printed dipoles on grounded planar dielectric slabs. A new method for predicting the scan blindness angles using the average scan impedances of a subsection of dipoles at the center of the array is introduced. A hybrid method of moments/Green's function technique is used to analyze the finite arrays of printed dipoles. Several numerical results are presented to demonstrate the accuracy of the new method in terms of predicting the blindness angle. © 2011 EurAAP.
