Optical Responses From Zero Optical‐Path‐Length Object
Nanophotonics, Volume 15, Issue 15, 13 August 2026.This work address a fundamental question—what is the ultimately minimal embodiment of optical objects that produce useful optical effects? In fact, such an object does not require nonzero physical and optical‐path‐length volume as opposed to the conventional perception.

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

Advanced Photonics Research, Volume 7, Issue 8, August 2026.A plasmonic metasurface comprising gold cylinders of tailored dimensions exhibits simultaneously the generalized Kerker effect and a bound state in the continuum, allowing for a detailed study of the subtle interplay between these phenomena. The numerical simulation results are in good agreement with experimental measurements, and the underlying ...

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 ...

Advanced Science, Volume 13, Issue 44, 7 August 2026.A nanoparticle‐cluster‐on‐mirror (NPcoM) serves as a functionally deterministic sub‐nanocavity that emulates picocavities, enabling extreme light–matter interactions and polaritonic phenomena. ABSTRACT Pushing nanoscale optical confinement to its ultimate limits defines the regime of nano‐cavity quantum electrodynamics (nano‐cQED), where light‐matter ...

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.

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 ...

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
