Metasurfaces, a two-dimensional (2D) form of metamaterials constituted by planar meta-
atoms, exhibit exotic abilities to tailor electromagnetic (EM) waves freely. Over the past …

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 …

Structures with near-zero parameters (for example, media with near-zero relative permittivity
and/or relative permeability, and thus a near-zero refractive index) exhibit a number of …

Bound states in the continuum (BICs),–are peculiar topological states that, when realized in
a planar photonic crystal lattice, are symmetry-protected from radiating in the far field despite …

The realization of high-Q resonances in a silicon metasurface with various broken-symmetry
blocks is reported. Theoretical analysis reveals that the sharp resonances in the …

Exciton–polaritons derived from the strong light–matter interaction of an optical bound state
in the continuum with an excitonic resonance can inherit an ultralong radiative lifetime and …

We present the experimental observation of bound states in the continuum. Our experiments
are carried out in an optical waveguide array structure, where the bound state (guided …

Waves that are perfectly confined in the continuous spectrum of radiating waves without
interaction with them are known as bound states in the continuum (BICs). Despite recent …

In the past ten years, the ideas of supersymmetry have been profitably applied to many
nonrelativistic quantum mechanical problems. In particular, there is now a much deeper …

Abstract Bound-states-in-the-continuum (BIC) is an emerging concept in nanophotonics with
potential impact in applications, such as hyperspectral imaging, mirror-less lasing, and …
