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…
Phase-Gradient Huygens Metasurface Coatings for Dynamic Beamforming in Linear Antennas
Stefano Vellucci, Michela Longhi, Alessio Monti +3
The beamforming capabilities of conformal cylindrical Huygens metasurface (HMS) coatings for linear antennas are assessed. It is shown that by engineering the phase-gradient profil…
Pulse-Driven Self-Reconfigurable Meta-Antennas
Daiju Ushikoshi, Riku Higashiura, Kaito Tachi +11
Wireless communications and sensing have notably advanced thanks to the recent developments in both software and hardware. Although various modulation schemes have been proposed to…
Quadratic-Gradient Metasurface-Dome for Wide-Angle Beam Steering Phased Array with Reduced Gain-Loss at Broadside
Alessio Monti, Stefano Vellucci, Mirko Barbuto +5
The quest for increasing the scanning range of a phased array is a challenging task for antenna engineers, and its solution could lead to significant advances in different applicat…
Metasurfaces 3.0: a New Paradigm for Enabling Smart Electromagnetic Environments
Mirko Barbuto, Zahra Hamzavi-Zarghani, Michela Longhi +5
So far, the environment has been considered as a source of fading, clutter, blockage, etc., with detrimental consequences for the efficiency and robustness of communication systems…
