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,…
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…
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…
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…
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…
Waveform-Selective Mantle Cloaks for Intelligent Antennas
Stefano Vellucci, Alessio Monti, Mirko Barbuto +2
We present the design of an innovative wire antenna able to automatically hide or reveal its presence depending on the waveform of the received/transmitted signal. This unconventio…
A Topological Design Tool for the Synthesis of Antenna Radiation Patterns
Mirko Barbuto, Mohammad-Ali Miri, Andrea Alù +2
Patch antennas are among the most popular radiating elements, yet their quasi-2-D structure reduces the degrees of freedom available to tailor their radiation pattern. To overcome…
Waveguide Components and Aperture Antennas With Frequency- and Time-Domain Selectivity Properties
Mirko Barbuto, Daniele Lione, Alessio Monti +3
Filtering modules are essential devices of modern microwave systems given their capability to improve the signal-to-noise ratio of the received signal or to eliminate the unwanted…
