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…
Generalized Director Approach for Liquid-Crystal-Based Reconfigurable RF Devices
Antonio Alex-Amor, Angel Palomares-Caballero, Antonio Palomares +3
This letter presents a closed-form integral-equation formulation that models the director tilting in nematic liquid crystals. The proposed formulation is computationally efficient…
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…
