“…One is to compute a specific FSS in its entirety [9] and the other is to cascade the generalized scattering matrices (GSMs) of the constitutive building blocks [10]. Recently, the boundary-integral-resonant-mode expansion (BI-RME), used to compute the entire-domain basis functions in conjunction with method of moments (MoM), has been applied to analysis of FSSs [11].…”

Abstract-We present a space-domain integral-equation method for the analysis of periodic structures formed by three-dimensional (3-D) metallic objects arranged in a general skewed two-dimensional lattice. The computation of the space-domain Green's function is accelerated using the Ewald transformation. The method is validated on several periodic structures ranging from planar frequency-selective surfaces to 3-D photonic crystals and metamaterials. For these structures, our technique shows a clear advantage in terms of computational speed when compared with available commercial softwares.Index Terms-Frequency-selective surfaces (FSSs), Green's functions (GFs), integral equations (IEs), metamaterials, periodic structures, photonic-bandgap (PBG) materials.

Abstract-In this paper, we present the space-domain integralequation method for the analysis of frequency selective surfaces (FSS), consisting of an array of periodic metallic patches or a metal screens perforated periodically with arbitrarily shaped apertures. The computation of the spatial domain Green's function is accelerated by the Ewald transformation. The geometric model is simplified by the lattice symmetry, so that the unknowns are greatly reduced. Time of filling MOM matrix and solving linear system is dramatically reduced. Our technique shows much higher efficiency when compared with the available commercial software and the existing methods published.

“…The corresponding virtual WG is referred to here as the PBC-WG, in which the incident and reflected fields are expanded into so-called Floquet harmonics [17]. By placing only one cell in the PBC-WG, and assuming that the array lattice simulated corresponds to a reflectarray free of grating lobes for any scan angle above the ground plane , the PBC-WG supports two orthogonal nonevanescent Floquet harmonics, which provides information on the co-and cross-polarization of the element.…”

Abstract-This paper presents new contributions to the modeling and design of reflecting cells embedding discrete control elements such as microelectromechanical system (MEMS) or diodes. First, a rigorous assessment of the different possibilities to simulate and measure the reconfigurable cell in a periodic environment is proposed. Strategies to efficiently model a cell comprising discrete control elements are then presented and discussed in terms of versatility, required assumptions, and computational effort. The most efficient method allows computing all reconfigurable states cell parameters, including information such as the total and dissipated power in each MEMS or diode, in a few minutes using a commercial full-wave solver and adequate post-processing. Finally, the benefit of such an efficient modeling is illustrated by the optimization of an element phase states distribution using a particle swarm optimizer. The concepts presented are also directly applicable to reconfigurable transmitting cells.
