Structural symmetry plays a pivotal role in the emergence of symmetry-protected bound
states in the continuum (BICs), often observed at the Γ-point within the first Brillouin zone …

Symmetry-protected bound states in the continuum (SP-BICs) are one of the most intensively
studied BICs. Typically, SP-BICs must be converted into quasi-BICs (QBICs) by breaking the …

Oligomer metasurfaces have attracted a lot of attention in recent years because of their
ability to drive strong resonance effects. In this work, by perturbing the symmetry of the …

Dielectric metasurfaces supporting symmetry-protected bound states in the continuum (SP-
BICs) have emerged as an attractive platform for manipulating light–matter interactions on …

It is well established that for symmetry‐protected bound states in the continuum (BICs),
introducing the broken geometry symmetry in a dielectric metasurface transforms such a BIC …

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 …

High-Q resonances driven by quasi-bound states in the continuum (quasi-BIC) in
metasurfaces have recently attracted much attention in the field of photonics. This work …

Bound states in the continuum (BICs) have been thoroughly investigated due to their
formally divergent Q‐factor, especially those emerging in all‐dielectric, nanostructured …

As optical resonances with high-quality (Q) factors, bound states in the continuum (BICs)
supported in a metamaterial with low optical loss have attracted great interest due to their …

Resonant dielectric metasurfaces have been demonstrated to hold a great promise for
manipulation of light-wave dispersion at the nanoscale due to their resonant photonic …
