Abstract

A method for the optimization of the crosspolar component of dual-polarized reflectarrays using the Method of Moments (MoM) is described. It is based on the LevenbergMarquardt Algorithm (LMA) and it exploits several optimization techniques to accelerate the computations in order to be able to use MoM within acceptable computing times. Since MoM is used to analyze the reflectarray unit cell, it accurately accounts for the crosspolar components of the radiated far field, which can then be optimized in order to reduce its value while preserving the copolar shape. A test case is provided to validate the developed algorithm in which a Local Multipoint Distribution Service (LMDS) pattern is optimized.
