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 …

All-dielectric metasurfaces have been intensively researched as a low-loss, flat-optics
platform for the advanced manipulation of electromagnetic wave propagation. Among the …

Symmetry‐protected quasi‐bound states in the continuum (BIC) controlled by metasurfaces
with broken in‐plane symmetry are widely exploited to achieve highly surface‐sensitive and …

In this Letter, we propose a symmetric metasurface composed of single-sized amorphous-
silicon (a-Si) cuboids tetramer clusters that support two resonances with opposite symmetry …

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 …

Sensing is a crucial step to provide information for biology and chemistry. The introduction of
a new method with high sensitivity, robustness and low cost has been a research hotspot …

In this paper, an all-dielectric metasurface that measures refractive index and temperature
using silicon disks is presented. It can simultaneously produce three resonances excited by …

We theoretically and experimentally investigate a metasurface supporting a silicon-slot
quasi-bound state in the continuum (qBIC) mode resonating in the near-infrared spectrum …

Ultra-high quality (Q) factor resonances derived from the bound states in the continuum
(BICs) have drawn much attention in optics and photonics. Especially in meta-surfaces, they …

Various optical phenomena can be induced in periodic arrays of nanoparticles by the
radiative coupling of the local dipoles in each particle. Probably the most impressive …
