Abstract

A fast spectral-domain approach using Macro Basis Functions is proposed to directly obtain the reduced impedance matrix for large regular and irregular arrays with non-identical elements. The developed method is tested considering a designed reflectarray system, which consists of a large number of non-identical dipoles printed on a multilayered substrate. The computational complexity related to the reduced matrix filling time during a Method-of-Moments process is greatly reduced.
