All-dielectric metamaterials and metasurfaces have been demonstrated as ideal platforms to
manipulate electromagnetic waves and enhance light–matter interaction. Analogous to …

Nonradiating sources of energy have traditionally been studied in quantum mechanics and
astrophysics but have received very little attention in the photonics community. This situation …

It is well established that for symmetry‐protected bound states in the continuum (BICs),
introducing the broken geometry symmetry in a dielectric metasurface transforms such a BIC …

Metasurfaces based on resonant subwavelength photonic structures enable novel ways of
wavefront control and light focusing, underpinning a new generation of flat-optics devices …

We reveal that metasurfaces created by seemingly different lattices of (dielectric or metallic)
meta-atoms with broken in-plane symmetry can support sharp high-Q resonances arising …

Symmetry-protected bound states in the continuum (BICs) are nonradiative states with
infinite lifetime and perfect confinement of energy even though lying in the radiation …

Harnessing the power of symmetry‐protected bound states in the continuum (SP BICs) has
become a focal point in scientific exploration, promising many interesting applications in …

High quality (Q) factor optical resonators are indispensable for many photonic devices.
While very large Q-factors can be obtained theoretically in guided-mode settings, free-space …

An important topic of modern nanophotonics focuses on the bound states in the continuum
(BIC) that the non-radiative localized waves lie within the radiative continuous spectrum …

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 …
