Observation of fano resonances in all-dielectric nanoparticle oligomers
, 2014 It is well-known that oligomers made of metallic nanoparticles are able to support sharp Fano resonances originating from the interference of two plasmonic resonant modes with different spectral width.

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

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

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 ...

Fano resonance in concentric ring apertures
Optics Express, 2013 We demonstrate a polarization-independent mid-infrared Fano resonance with extraordinary transmission when light passes through two concentric metallic ring apertures. A high-Q dark mode is indirectly excitated by coupling with a low-Q bright mode. A coupled optical resonator model is used to analyze the coupling process between the bright and dark ...

Strong Mode Coupling and Maximum Directional Absorption in Reciprocal Bianisotropic Metasurfaces
Nanophotonics, Volume 15, Issue 12, 25 June 2026.Symmetry breaking in q‐BIC dielectric metasurfaces enables strong electromagnetic coupling between electric and magnetic modes, leading to their hybridization and Rabi‐like splitting. This mechanism produces pronounced reciprocal bianisotropy and dual‐band asymmetric absorption under opposite illumination directions, offering a compact framework for ...

Widening of the large-angle half-wave wall through a pair of parameter-reversal Fano resonances
Materials & DesignWith the high quality (Q) factor, the Fano resonance has only been focused on sensing and switching, while its value in other fields ignored. In this manuscript, according to the Fano spectral characteristics, we have first proposed to use the Fano ...

Dramatic and Elusive Resonant Lattice Kerker Effect in the Nonlinear Response of Plasmonic Lattices
Nanophotonics, Volume 15, Issue 12, 25 June 2026.Plasmonic metasurface that supports the resonant lattice Kerker effect, manifesting as the suppression of reflection in a narrow spectral range due to the simultaneous excitation of electric dipole and quadrupole modes, also gives rise to a substantial near‐field enhancement.
