Time-Controlled Resonances in 2-D Metasurfaces via Equivalent Circuits
J. Rafael Sánchez-Martínez, Mario Pérez-Escribano, Antonio Alex-Amor +2
This work introduces a semi-analytical frequency-domain framework for the analysis of two-dimensional, time-modulated (2+1)-D metasurfaces controlled by PIN diodes. The formulation…
Enabling 6G Wireless Communications: UWB Characterization of Corridors within the H-Band
Juan E. Galeote-Cazorla, Alejandro Ramírez-Arroyo, Mauricio Rodríguez +2
Future sixth-generation of wireless system is expected to provide data-rates in the order of 1 Tbps and latencies below 1 ms. Among others, one of the most promising strategies to…
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…
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…
Joint Direction-of-Arrival and Time-of-Arrival Estimation with Ultra-wideband Elliptical Arrays
Alejandro Ramírez-Arroyo, Antonio Alex-Amor, Pablo Padilla +1
This paper presents a general technique for the joint Direction-of-Arrival (DoA) and Time-of-Arrival (ToA) estimation in multipath environments. The proposed ultra-wideband techniq…
