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 …

Enhancing the light‐matter interactions is important for many different applications like
sensing, surface enhanced spectroscopies, solar energy harvesting, and for quantum effects …

Toroidal moment is an electromagnetic excitation that lies outside the familiar picture of
electric and magnetic multipoles. It has recently been a topic of intense research in the fields …

Modern nanophotonics has witnessed the rise of “electric anapoles”(EDAs), destructive
interferences of electric and toroidal electric dipoles, actively exploited to resonantly …

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 …

In this work, a novel all-dielectric metasurface made of arrayed circular slots etched in a
silicon layer is proposed and theoretically investigated. The structure is designed to support …

Both toroidal dipoles, electric dipoles and magnetic dipoles belong to one type of
electromagnetic excitation. In this paper, we present an all-dielectric metasurface composed …

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 …

The size parameter q= 2π R/λ in spheres with a radius R=(2–3) λ (λ is the radiation
wavelength) is on the order of 10. Strong Mie resonances () are observed in these …

In this work, a silicon metasurface designed to support electromagnetically induced
transparency (EIT) based on quasi-bound states in the continuum (qBIC) is proposed and …
