A Dual-Mode FM/AM Modulator Based on a Time-Varying Inverting Integrator
Azalía G. Gil, Alfonso T. Muriel-Barrado, Mario Pérez-Escribano +2
This paper presents the analysis, design, fabrication, and experimental validation of a dual-mode frequency/amplitude modulator based on a time-modulated varactor diode. By exploit…
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…
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…
