Tunable Bound States in the Continuum in All-Dielectric Terahertz Metasurfaces
Nanomaterials, 2020 In this paper, a tunable terahertz dielectric metasurfaces consisting of split gap bars in the unit cell is proposed and theoretically demonstrated, where the sharp high-quality Fano resonance can be achieved through excitation of quasi-bound states in ...

Engineering Fano resonances in discrete arrays [PDF]
Physical Review E, 2005 We study transmission properties of discrete arrays composed of a linear waveguide coupled to a system of side defect states. This simple system can be used to model discrete networks of coupled defect modes in photonic crystals, complex waveguide arrays in two-dimensional nonlinear lattices, and ring-resonator structures.

Advanced Physics Research, EarlyView.This study presents toroidal‐dipole (TD)‐driven polarisation‐selective quasi‐bound states in the continuum (quasi‐BICs) in all‐dielectric metasurfaces, enabling transverse magnetic (TM)‐selective excitation with ultrahigh quality factors and wide‐angle‐stable polarisation‐dependent near‐field imaging.

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 Physics Research, EarlyView.The investigation of the Kondo lattice system CeB6${\rm CeB}_6$ by highly surface sensitive techniques is hampered by difficulties in preparing well‐ordered, atomically flat surfaces. The richness of possible surface terminations and their impact on spectroscopic STM results are discussed.

, 2010 We study the zero-bias conductance through the system of two quantum dots, one of which is embedded directly between the source and drain electrodes, while the second dot is side-coupled to the first one through a tunneling junction.

Anisotropy-induced Fano resonance
, 2012 An optical Fano resonance, which is caused by birefringence control rather than frequency selection, is discovered. Such birefringence-induced Fano resonance comes with fast-switching radiation. The resonance condition $\varepsilon_t< 1/\varepsilon_r$ is revealed and a tiny perturbation in birefringence is found to result in a giant switch in the ...

Hydrogen Halide Gas Sensors: Active Materials, Operation Principles, and Emerging Technologies
Interdisciplinary Materials, EarlyView.This review considers hydrogen halide (HX) gas sensors across functional materials and principles: acoustic, chemical, optical and nanophotonic. The strong acidity and reactivity of HX gases are discussed as constraints for stability and selectivity of these devices.

Fano-Kondo interplay in a side-coupled double quantum dot
, 2009 We investigate low-temperature transport characteristics of a side-coupled double quantum dot where only one of the dots is directly connected to the leads.
