Time-periodic Metallic Metamaterials defined by Floquet Circuits
Salvador Moreno-Rodríguez, Antonio Alex-Amor, Pablo Padilla +2
In this paper, we study the scattering and diffraction phenomena in time-modulated metamaterials of metallic nature by means of Floquet equivalent circuits. Concretely, we focus on…
Cross-polarization Control in FSSs by means of an Equivalent Circuit Approach
Carlos Molero, Antonio Alex-Amor, Francisco Mesa +2
This paper presents an efficient equivalent circuit approach (ECA), based on a Floquet modal expansion, for the study of the co- and cross-polarization in frequency selective surfa…
Glide-Symmetric Metallic Structures with Elliptical Holes for Lens Compression
Antonio Alex-Amor, Fatemeh Ghasemifard, Guido Valerio +4
In this paper, we study the wave propagation in a metallic parallel-plate structure with glide-symmetric elliptical holes. To perform this study, we derived a mode-matching techniq…
Dispersion and Filtering Properties of Rectangular Waveguides Loaded With Holey Structures
Ángel Palomares-Caballero, Antonio Alex-Amor, Pablo Padilla +1
This paper analyzes thoroughly the dispersion and filtering features of periodic holey waveguides in the millimeter-wave frequency range. Two structures are mainly studied dependin…
Exploring the Potentials of the Multi-modal Equivalent Circuit Approach for Stacks of 2-D Aperture Arrays
Antonio Alex-Amor, Francisco Mesa, Ángel Palomares-Caballero +2
Many frequency selective surface (FSS) structures are based on the use of a single periodic array of slot/apertures in a conducting sheet embedded in a layered medium. However, it…
