Theory of Spoof Magnetic Localized Surface Plasmons Beyond Effective Medium Approximations
Carlo Rizza, Angelo Galante, Elia Palange +1
A homogeneous negative permeability sphere can support magnetic localized surface plasmons (MLSPs). Generally, negative permeability materials are metamaterial (MM) structures exhi…
Diode-like asymmetric transmission in ultrathin hyperbolic epsilon-near-zero slabs: extreme anisotropy mimicking chirality
Carlo Rizza, Xin Li, Andrea Di Falco +3
We demonstrate that a strong asymmetric transmission for forward and backward propagation of tilted circular polarized optical waves is supported by ultrathin epsilon-near-zero hyp…
Reconfigurable photoinduced metamaterials in the microwave regime
Carlo Rizza, Alessandro Ciattoni, Francesco De Paulis +4
We investigate optically reconfigurable dielectric metamaterials at gigahertz frequencies. More precisely, we study the microwave response of a subwavelength grating optically impr…
Tunable electromagnetic chirality induced by graphene inclusions in multi-layered metamaterials
Carlo Rizza, Elia Palange, Alessandro Ciattoni
We theoretically investigate the electromagnetic response of a novel class of multi-layered metamaterials obtained by alternating graphene sheets and dielectric layers, the whole s…
All-optical active plasmonic devices with memory and power switching functionalities based on epsilon-near-zero nonlinear metamaterials
Alessandro Ciattoni, Carlo Rizza, Elia Palange
All-optical active plasmonic devices are of fundamental importance for designing efficient nanophotonic circuits. We theoretically propose and numerically investigate an active pla…
Two-peaked and flat-top perfect bright solitons in epsilon-near-zero nonlinear metamaterials: novel Kerr self-trapping mechanisms
Alessandro Ciattoni, Carlo Rizza, Elia Palange
We analytically investigate transverse magnetic (TM) spatial bright solitons, as exact solutions of Maxwell's equations, propagating through nonlinear metamaterials whose linear di…
