Terahertz tunable graphene Fano resonance
Nanotechnology, 2016By depositing graphene circular double rings (DR) on a SiO2/Si/polymer substrate, the tunable Fano resonance has been theoretically investigated in the terahertz regime, including the effects of the graphene Fermi level, structural parameters and operation frequency.

The Friedel sum rule at Fano resonances
Journal of Physics: Condensed Matter, 2009If a mesoscopic system is non-chaotic or non-ergodic then the thermodynamic and transport properties do not depend on the impurity averaged density of states. We show that the partial density of states as well as the density of states of a given system with a given impurity configuration can be determined exactly from the asymptotic wavefunction (or ...

Fanoshells: Nanoparticles with Built-in Fano Resonances
Nano Letters, 2010A nanoparticle consisting of a dielectric (SiO(2)) and metallic (Au) shell layer surrounding a solid Au nanoparticle core can be designed with its superradiant and subradiant plasmon modes overlapping in energy, resulting in a Fano resonance in its optical response.

Plasmonic Systems Unveiled by Fano Resonances
ACS Nano, 2012We show in detail how a derivation of Fano theory can serve as a new paradigm to study, understand, and control the interaction of nano-objects with light. Examples include a plasmonic crystal, a dolmen-type structure sustaining dark and bright plasmon modes, and a nanoshell heptamer.

Optical Fano resonances in a nonconcentric nanoshell
Applied Optics, 2016The interaction of light with a metal nanoshell with an off-center core generates multipoles of all orders. We show here that the matrix elements used to compute the multipole expansion coefficients can be derived analytically and, with this result, we can show explicitly how the dipole and quadrupole terms in the expansion are coupled and give rise to
