Modeling of reactive impedance surface´s diffraction with application of MoM-GEC method

In this paper, we propose the study of reactive impedance surface (RIS), used especially as reflector for antenna miniaturization, with MoM-GEC method. The electromagnetic modeling using integral methods, such as MoM-GEC, is of great interest because they are the most appropriate to study planar structures, since they provide the reduction of the problem´s dimension. Hence, they permit the gain in memory storage and computational time. In this context, we study with details the behavior of RIS against incidence and polarization. Numerical results are shown, discussed and compared with literature and FSS software.
