Resumen

Different strategies for the discretization of the angles of incidence and its influence on reflectarray analysis based on surrogate models with support vector regression (SVR) are studied. One SVR per pair of angles of incidence is considered, and it is shown that while the copolar pattern is robust against the discretization of the angle of incidence, the crosspolar pattern presents a higher sensitivity with regard to the baseline scenario
