The introduction of bound states in the continuum (BICs) to photonics has revolutionized the
way cavity design and light–matter interactions are thought about in general. BICs can have …

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 …

Non-radiative bound states in the continuum (BICs) allow construction of resonant cavities
with confined electromagnetic energy and high-quality (Q) factors. However, the sharp …

I review the four mechanisms of bound states in the continuum (BICs) in the application of
microwave and acoustic cavities open to directional waveguides. The most simple are …

Metasurfaces have attracted a lot of attention in recent years due to the alternative methods
they provide for the efficient wavefront control and engineering of resonant transmission. We …

Bound states in the continuum (BICs) are a striking example of how a solution to a simple
problem of quantum mechanics, obtained about a century ago, can serve as an incentive to …

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 …

Bound states in the continuum (BICs) are counterintuitive localized states with eigenvalues
embedded in the continuum of extended states. Recently, nontrivial band topology is …

A second-order topological insulator is designed on a platform of a two-dimensional (2D)
square lattice with all coupling coefficients having the same sign. Simulated results show the …

We show that lattices with higher-order topology can support corner-localized bound states
in the continuum (BICs). We propose a method for the direct identification of BICs in …
