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,…

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…
