From theoretical model to experimental realization, the bound state in the continuum (BIC) is
an emerging area of research interest in the last decade. In the initial years, well-established …

Bound states in the continuum (BICs) are waves that remain localized even though they
coexist with a continuous spectrum of radiating waves that can carry energy away. Their very …

We demonstrate that rotationally symmetric chiral metasurfaces can support sharp
resonances with the maximum optical chirality determined by precise sha** of bound …

Optical bound states in the continuum (BICs) have recently stimulated a research boom,
accompanied by demonstrations of abundant exotic phenomena and applications. With …

We present the first experimental demonstration of a new type of localized state in the
continuum, namely, compacton-like linear states in flat-band lattices. To this end, we employ …

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 …

We propose and experimentally realize a new kind of bound states in the continuum (BICs)
in a class of systems constructed by coupling multiple identical one-dimensional chains …

We study flat bands in bipartite tight-binding networks with discrete translational invariance.
Chiral flat bands with chiral symmetry eigenenergy E= 0 and host compact localized …

Planar chiral metasurfaces have emerged as a versatile platform for manipulating chiral light‐
matter interactions in diverse applications. However, it remains challenging to achieve high …

We consider a one-dimensional photonic crystal composed of alternating layers of isotropic
and anisotropic dielectric materials. Such a system has different band structures for different …
