Here, Ntot is the total number of unknowns. Numerical results for both printed and free-standing dipole arrays are presented to validate the algorithm's efficiency and accuracy.Discrete Fourier transform; Iterative solvers; Method of moments; Phased arrayEfficient analysis of large phased arrays using iterative MoM with DFT-based acceleration algorithmjournal article10.1002/mop.11136
