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…
