Space-time Metallic Metasurfaces for Frequency Conversion and Beamforming
Salvador Moreno-Rodríguez, Antonio Alex-Amor, Pablo Padilla +2
This paper details a class of metal-based space-time metasurfaces for application in wireless communications scenarios. Concretely, we describe space-time metasurfaces that periodi…
Analytical Framework to Model Reconfigurable Metasurfaces including Lumped Elements
Mario Pérez-Escribano, Salvador Moreno-Rodríguez, Carlos Molero +3
This paper presents an analytical framework, based on Floquet modal expansions of the electromagnetic fields and equivalent circuits, to model reconfigurable metasurfaces loaded wi…
Three-Dimensional Fully Metallic Dual Polarization Frequency Selective Surface Design Using Coupled-Resonator Circuit Information
Ignacio Parellada-Serrano, Mario Pérez-Escribano, Carlos Molero +2
This work employs a new approach to analyze coupled-resonator circuits to design and manufacture a fully metallic dual polarization frequency selective surface (FSS). The proposed…
Analytical Equivalent Circuits for Three-dimensional Metamaterials and Metagratings
Antonio Alex-Amor, Salvador Moreno-Rodríguez, Pablo Padilla +2
In recent times, three-dimensional (3D) metamaterials have undergone a revolution driven mainly by the popularization of 3D-printing techniques, which has enabled the implementatio…
Analysis of Metallic Space-Time Gratings using Lorentz Transformations
Antonio Alex-Amor, Carlos Molero, Mário G. Silveirinha
This paper presents an analytical framework for the study of scattering and diffraction phenomena in spacetime-modulated metallic gratings. Using a Lorentz transformation, it is sh…
