Bound states in the continuum (BICs) have attracted considerable attentions for biological
and chemical sensing due to their infinite quality (Q)-factors in theory. Such high-Q devices …

Bound states in the continuum (BIC) have garnered considerable attention recently for their
unique capacity to confine electromagnetic waves within an open or non-Hermitian system …

Although numerous natural materials exhibit chiral optical phenomena, they are typically
very weak. Chiral nanophotonic structures can significantly enhance the chiroptical …

Metamaterials‐based sensors are of primary interest in physics, materials science,
medicine, and biophysics thanks to their ability to detect very tiny amount of molecules …

Measurements of the refractive index of liquids are in high demand in numerous fields such
as agriculture, food and beverages, and medicine. However, conventional ellipsometric …

This work presents a bulk refractive index sensor based on quasi-bound states in the
continuum (BICs) induced by broken symmetries in metasurfaces. The symmetry is broken …

Bound states in the continuum (BICs) in open cavities have attracted considerable attention
in wave physics due to their ability to confine light and produce high-quality-factor …

Bound states in the continuum (BICs) are zero-width (infinite lifetime) trapped eigenmodes
that remain confined in the system even though they coexist with a continuum of extended …

Herein, we realize quasi-bound states in the continuum (quasi-BICs) in a compound grating
waveguide structure with a complex lattice. The first layer of the structure is a grating layer …

An anisotropic photonic crystal containing two anisotropic defect layers is considered. It is
demonstrated that the system can support a Fabry-Perot bound state in the continuum (FP …
