Abstract :
In this paper, an extension of the forward-backward (FB) with DFT (discrete Fourier transform) based acceleration approach is presented to provide a relatively efficient analysis of EM radiation/scattering from an electrically large, planar, periodic, finite printed dipole array. Computational complexity of this new approach is O(Ntot), where Ntot is the number of elements in the array.
