Sharp Fano resonances in THz metamaterials
Optics Express, 2011 We report on the occurrence of sharp Fano resonances in planar terahertz metamaterials by introducing a weak asymmetry in a two gap split ring resonator. As the structural symmetry of the metamaterial is broken a Fano resonance evolves in the low-frequency flank of the symmetric fundamental dipole mode resonance.

IEEE Photonics Journal, 2017 A plasmonic resonator system composed of a metal-insulator-metal waveguide coupled with a disk and a ring cavity was proposed to produce double Fano resonances, which resulted from the coupling between the narrow discrete resonances of the ring cavity ...

The multi-photon induced Fano effect
Nature Communications, 2021 Fano resonances occur in many platforms that have auto-ionizing states. Here the authors show that auto-ionizing states are not required for multi-photon Fano resonance in a Si:P system with significant screening by using a pump-probe method.

Perforation Enhances Sound Insulation in Plate Lattice Metamaterials
Small, EarlyView.Herein, perforations are engineered into face‐centered cubic plate lattice metamaterials to convert normally detrimental openings into acoustically active features. Experiments, finite‐element analyses, and a reduced‐order transfer‐matrix model show that selected perforation geometries activate Helmholtz‐like and cavity‐mediated resonances, enhancing ...

Sensing Based on Fano-Type Resonance Response of All-Dielectric Metamaterials
Sensors, 2015 A new sensing approach utilizing Mie resonances in metamaterial arrays composed of dielectric resonators is proposed. These arrays were found to exhibit specific, extremely high-Q factor (up to 15,000) resonances at frequencies corresponding to the lower

Small, EarlyView.A slightly buckled 2D kagome metal‐organic framework (MOF) adsorbed on Ag(111) hosts localized spins which are Kondo‐screened by the underlying metal substrate. Using the tip of a scanning tunneling microscope, the MOF can be vertically manipulated to controllably change its adsorption height and with it, the Kondo coupling strength.

Double Fano Resonances in S-Shaped Plasmonic Metasurfaces in Terahertz Region
Frontiers in Physics, 2020 We numerically and experimentally demonstrated double Fano resonances in a simple S-shaped plasmonic metasurface in the terahertz frequency range. Apart from the electric-LC resonance and electric dipole (ED) resonance, two trapped modes are excited in ...

Plasmonic Spectral Splitting in Ring/Rod Metasurface
Nanomaterials, 2017 We report spectral splitting behaviors based on Fano resonances in a novel simple planar metasurface composed of gold nanobars and nanorings. Multiple plasmonic modes and sharp Fano effects are achieved in a broadband transmittance spectrum by exploiting
