Mie scattering as a cascade of Fano resonances
Optics Express, 2013 We reveal that the resonant Mie scattering by high-index dielectric nanoparticles can be presented through cascades of Fano resonances. We employ the exact solution of Maxwell's equations and demonstrate that the Lorenz-Mie coefficients of the Mie problem can be expressed generically as infinite series of Fano functions as they describe interference ...

Multiple Fano Resonances Based on End-Coupled Semi-Ring Rectangular Resonator
IEEE Photonics Journal, 2019 In this paper, multiple Fano resonances based on semi-ring-rectangular composite cavity (SRRCC) structure are numerically investigated and explained by the finite-difference time-domain method and the multiple interference coupled mode theory method ...

Tunable Fano Resonance and Enhanced Sensing in Terahertz Metamaterial
Frontiers in Physics, 2021 Fano resonances in metamaterial are important due to their low-loss subradiant behavior that allows excitation of high quality (Q) factor resonances extending from the microwave to the optical bands.

Fano Resonances with Discrete Breathers [PDF]
Physical Review Letters, 2003 A theoretical study of linear wave scattering by time-periodic spatially localized excitations (discrete breathers (DB)) is presented. We obtain that the wave propagation is strongly influenced by a local coupling between an open and closed channels generated by the DB.

Multiple Fano resonances excitation on all-dielectric nanohole arrays metasurfaces.
Optics Express, 2021 Both toroidal dipoles, electric dipoles and magnetic dipoles belong to one type of electromagnetic excitation. In this paper, we present an all-dielectric metasurface composed of an array of square nanoholes. It can simultaneously generate four resonance

Fano resonances in nanoscale structures [PDF]
, 2009 Modern nanotechnology allows one to scale down various important devices (sensors, chips, fibers, etc.) and thus opens up new horizons for their applications. The efficiency of most of them is based on fundamental physical phenomena, such as transport of

Fano resonances in quantum transport with vibrations [PDF]
Physical Review A, 2021 Quantum mechanical scattering involving continuum states coupled to a scatterer with a discrete spectrum gives rise to Fano resonances. Here we consider scatterers that possess internal vibrational degrees of freedom in addition to discrete states. Entanglement between the scattered excitation and vibrational modes complicates analytical and numerical ...

Deep Learning-Assisted Enhanced Fano Resonances in Symmetry-Breaking SOI Metasurface
IEEE Photonics Journal, 2022 Metasurfaces analogues of Fano resonances provide a powerful platform for high sensitivity sensing, nonlinear optics, and light manipulation. However, previous Fano-resonant metasurfaces usually are not compatible with silicon complementary metal-oxide ...
