This paper aims at contributing to the specialized literature on the experimental characterization of metasurfaces (MTSs) reflectivity. The growing demand for angularly stable MTSs reinforces the relevance of the results under oblique incidence. Gene
A new technique to retrieve the constitutive parameters of grounded metamaterials is proposed in this article. Previous methods presented in the literature used to retrieve the constitutive parameters of materials in general and metamaterials, in par
