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…
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…
Electromagnetic Isolation Induced by Time-Varying Metasurfaces: Non-Reciprocal Bragg Grating
Davide Ramaccia, Dimitrios L. Sounas, Angelica V. Marini +2
In this letter, we propose a magnet-less non-reciprocal isolating system based on time-varying metasurfaces. Two parallel time-varying metasurfaces, one for frequency up-conversion…
Phase-Induced Frequency Conversion and Doppler Effect with Time-Modulated Metasurfaces
Davide Ramaccia, Dimitrios L. Sounas, Andrea Alu' +2
Metasurfaces consisting of electrically thin and densely packed planar arrays of subwavelength elements enable an unprecedented control of the impinging electromagnetic fields. Spa…
