3-D Metamaterials: Trends on Applied Designs, Computational Methods and Fabrication Techniques
Antonio Alex-Amor, Angel Palomares-Caballero, Carlos Molero
Metamaterials are artificially engineered devices that go beyond the properties of conventional materials in nature. Metamaterials allow the creation of negative refractive indexes…
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…
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…
Low-Loss Reconfigurable Phase Shifter in Gap-Waveguide Technology for mm-Wave Applications
Á. Palomares-Caballero, A. Alex-Amor, P. Escobedo +2
In this brief, we present a low-loss mechanically reconfigurable phase shifter implemented in gap-waveguide technology for mm-wave frequencies. The proposed design gives a practica…
