Temporal multilayer structures for designing higher-order transfer functions using time-varying metamaterials
Davide Ramaccia, Andrea Alu, Alessandro Toscano +1
Temporal metamaterials are artificial materials whose electromagnetic properties change over time. In analogy with spatial media and metamaterials, where their properties change sm…
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…
Temporal Rainbow Scattering at Boundary-Induced Time Interfaces
L. Stefanini, D. Ramaccia, A. Toscano +1
Since the dawn of modern optics and electromagnetics, optical prism is one of the most fascinating optical elements for refracting light. Exploiting its frequency dispersive behavi…
Temporal interfaces by instantaneously varying boundary conditions
Luca Stefanini, Shixiong Yin, Davide Ramaccia +3
Temporal metamaterials have been recently exploited as a novel platform for conceiving several electromagnetic and optical devices based on the anomalous scattering response arisin…
Tunable scattering cancellation cloak with plasmonic ellipsoids in the visible
Martin Fruhnert, Alessio Monti, Ivan Fernandez-Corbaton +4
The scattering cancellation technique is a powerful tool to reduce the scattered field from electrically small objects in a specific frequency window. The technique relies on cover…
Plasmonic metamaterial cloaking at optical frequencies
Filiberto Bilotti, Simone Tricarico, Lucio Vegni
In this paper, we present the design of cylindrical and spherical electromagnetic cloaks working at visible frequencies. The cloak design is based on the employment of layered stru…
