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,…
Passive Time-Varying Waveform-Selective Metasurfaces for Attainment of Magnetic Property Control
Yuki Kunitomo, Kairi Takimoto, Stefano Vellucci +5
We present circuit-loaded metasurfaces that behave differently in a passive manner even at the same frequency in accordance with the incoming waveform, specifically, its pulse widt…
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…
On the Use of Nonlinear Metasurfaces for Circumventing Fundamental Limits of Mantle Cloaking for Antennas
Stefano Vellucci, Alessio Monti, Mirko Barbuto +4
The aim of this communication is to investigate and demonstrate the possibility to overcome the fundamental limitations of mantle cloaking for antennas by exploiting nonlinear meta…
