Generation-Agnostic Zero-Energy Devices for Sustainable Connectivity, Sensing, and Localization
Navid Amani, Filiberto Bilotti, Davide Dardari +7
The massive scale of Internet of Things (IoT) connectivity expected in 6G networks raises unprecedented challenges in energy use, battery waste, and lifecycle sustainability. Curre…
Tunable Transmissive Metagratings Using Single Layer Cylindrical Plasma Discharges
Mohammad G. H. Alijani, Alessio Monti, Stefano Vellucci +3
In this paper, we propose a novel single-layer reconfigurable transmissive metagrating based on plasma discharges. Each unit-cell consists of two side-by-side core-shell cylinders,…
Temporal multilayer structures for designing higher-order transfer functions using time-varying metamaterials
Davide Ramaccia, Andrea Alu, Alessandro Toscano +1
Temporal metamaterials are artificial materials whose electromagnetic properties change over time. In analogy with spatial media and metamaterials, where their properties change sm…
Metasurface Dome for Above-the-Horizon Grating Lobes Reduction in 5G-NR Systems
Davide Ramaccia, Mirko Barbuto, Alessio Monti +4
The use of 5G New Radio (NR) spectrum around 26 GHz is currently raising the quest on its compatibility with the well-established Earth Exploration-Satellite Service (EESS), which…
Perfect matching of reactive loads through complex frequencies: from circuital analysis to experiments
Angelica V. Marini, Davide Ramaccia, Alessandro Toscano +1
The experimental evidence of purely reactive loads impedance matching is here provided by exploiting the special scattering response under complex excitations. The study starts wit…
Propagation through metamaterial temporal slabs: transmission, reflection and special cases
Davide Ramaccia, Alessandro Toscano, Filiberto Bilotti
Time-varying metamaterials are artificial materials whose electromagnetic properties change over time. Similar to a spatial medium discontinuity, a sudden change in time of the met…
