The Friedel sum rule at Fano resonances

Journal of Physics: Condensed Matter, 2009
If 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 ...

The Fano resonance in plasmonic nanostructures and metamaterials

Nature Materials, 2010
Since its discovery, the asymmetric Fano resonance has been a characteristic feature of interacting quantum systems. The shape of this resonance is distinctively different from that of conventional symmetric resonance curves. Recently, the Fano resonance has been found in plasmonic nanoparticles, photonic crystals, and electromagnetic metamaterials ...

Fanoshells: Nanoparticles with Built-in Fano Resonances

Nano Letters, 2010
A 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.

Optical Fano resonances in a nonconcentric nanoshell

Applied Optics, 2016
The 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

Multiple fano resonances in an end-coupled MIM waveguide system

, 2019
In this paper, multiple tunable Fano resonances are firstly achieved in an end-coupled system composed of a rectangular cavity and an inverted U-shaped groove. Through increasing a coupling path, dual Fano resonances are tuned to four Fano peaks.
