BOUND statesPHONONIC crystalsFLUIDIC devicesThe significance of bound states in the continuum (BICs) lies in their potential for theoretically infinite quality factors. However, their actual quality factors are limited by imperfections in fabrication, which lead to coupling with the radiation continuum. ...
Toroidal multipole moments are usually underestimated as they are quite weak in most cases of light-matter interaction. Herein, we reveal a strong link between the toroidal dipole resonance and the bound state in the continuum in the context of all-dielectric metasurfaces. We introduce the concept...
Merging toroidal dipole bound states in the continuum without up-down symmetry in Lieb lattice metasurfaces The significance of bound states in the continuum (BICs) lies in their potential for theoretically infinite quality factors. However, their actual quality ......

Via control of the asymmetry of the cluster, the TD could transform from bound states in the continuum into leaky resonances with high-Q factors. The optical antiferromagnetic response could also be identified from the tetramer cluster arrays. The toroidal and antiferromagnetic effects come from the...
Among these, one exciting strategy is based on the hybridization of surface lattice resonances (SLRs). In this study, we investigated for the first time the Toroidal dipole bound states in the continuum (TD-BICs) based on the hybridization of Mie surface lattice resonances (SLRs) in an array...
Bound states in the continuum (BICs) are a special kind of resonant states that remain localized even though they coexist with a continuous spectrum of radiating waves. They have already emerged as an important design principle for creating systems with high-quality (Q) factor states to enhance ...
By modifying the unit structure of the metasurface with the bound states in the continuum (BICs), a sharp Fano resonance can be generated. The resonance properties of the metasurface are investigated by analyzing the effects of the structural parameters on the resonance using...

However, the excitation of...
The armchair metallic and semiconducting toroidal carbon nanotubes (TCNs) coupled with Majorana bound states (MBSs) under the perturbation of microwave fields (MWFs) have been investigated, and the photon-assisted features relating to tunneling current, differential conductance, and shot noise have been...
