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,…
Design of reconfigurable Huygens metasurfaces based on Drude-like scatterers operating in the epsilon-negative regime
Alessio Monti, Stefano Vellucci, Mirko Barbuto +4
In this study, we investigate the feasibility of designing reconfigurable transmitting metasurfaces through the use of Drude-like scatterers with purely electric response. Theoreti…
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…
