“…Bielli et al [23] did some FSS characterizations in a waveguide to check the validity of the FSS model that they developed. Pearson et al [24] proposed in 1996 to extend this concept to numerical simulations of FSS based on a finite-element modeling. More recently (in 2003), Mias [25] reported on tunable FSS with varactors that were characterized in free space and in a waveguide, but both measurements were not directly compared in his work.…”

International audienceThe possibility to characterize infinite and periodic frequency-selective surfaces (FSS) filters that have two orthogonal axes of symmetry inside a waveguide is reported. Thus, preliminary measurements can rapidly be obtained at low cost with few elementary cells instead of using a large FSS panel in free space. This is possible because of the equivalence that exists between the electromagnetic fields of two symmetric and oblique plane waves incident on and reflected from an infinite periodic surface and the incident/reflected fields that exist inside a single-mode rectangular waveguide containing a finite number of elementary cells. Comparisons of the measurements with some full-wave simulations for FSS belonging to the first three groups as they were defined by Munk confirm the good agreement between them. This is an interesting and simple assessment tool concerning the fabrication quality of FSS. The extension of this technique to non-symmetric FSS patterns is also discussed and supported by experimental and simulation results. The limitations of the technique are finally discussed

International audienceArtificial Magnetic Conductors (AMCs) design and characterization in the UHF band is a big challenge while realizing low-profile antenna. In fact, AMCs unit cell often balance large geometries with high dielectric constants to achieve the desired frequency target while maintaining a minimal thickness. A compact AMC unit cell achieving a 37% reduction in the largest dimension (or 60% of surface reduction) is proposed in this paper. Numerical technique is applied to simulate the behavior of the considered AMC and the conventional one based on mushroom-like unit cell. Two measurements methods in anechoic chamber (monostatic RCS and TEM cell measurements) have been compared to characterize the manufactured prototypes. Good agreement has been found between simulations and measurements. © 2017 IEEE
