Nanostructured surfaces with designed optical functionalities, such as metasurfaces, allow
efficient harvesting of light at the nanoscale, enhancing light–matter interactions for a wide …

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 …

Terahertz (THz) radiation encompasses a wide spectral range within the electromagnetic
spectrum that extends from microwaves to the far infrared (100 GHz–∼ 30 THz). Within its …

The concept of “bound states in the continuum”(BIC) describes an idealized physical system
exhibiting zero radiative loss composed, for example, of an infinitely extended array of …

Interference of electromagnetic modes supported by subwavelength photonic structures is
one of the key concepts that underpins the nanoscale control of light in metaoptics. It drives …

Toroidal multipole moments are usually underestimated as they are quite weak in most
cases of light-matter interaction. Herein, we reveal a strong link between the toroidal dipole …

Toroidal excitation manifests as currents flowing on the surface of a torus along its meridians
that are known as poloidal currents. Several intriguing phenomena such as nonradiating …

Toroidal moments in artificial media have received growing attention and considered as a
promising framework for initiating novel approaches to manage intrinsic radiative losses in …

In this paper, an innovative multitasking device (MTD) regulated by the gravity field realizing
the functions of metamaterial absorber (MMA) and linear polarization converter (LPC) is …

All-dielectric resonant nanophotonics lies at the heart of modern optics and nanotechnology
due to the unique possibilities to control scattering of light from high-index dielectric …
