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...
In this paper, we present a formulation based on surface impedance concept to model reactive impedance surface (RIS) applying the MoM-GEC method (MoM combined to generalized equivalent circuit). The study of the whole periodic infinite RIS is reduced to the unit cell modeling. We are interested especially in demonstrate the RIS impedance behavior against incidence and both TE and TM polarizations...
