All-dielectric metasurfaces have been intensively researched as a low-loss, flat-optics
platform for the advanced manipulation of electromagnetic wave propagation. Among the …

Biosensors have been designed and developed for detecting biomarkers, biomolecules,
proteins, enzymes, organisms, and various types of bacterial and viral diseases since the …

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 …

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 …

Numerous exciting optical effects in all-dielectric high-refractive-index structures are
associated with so-called toroidal electrodynamics. Among these effects are anapoles …

Since the performance of electronic circuits is becoming rather limited in face of intensively
increasing of amount of information and related operations, all‐optical processing offers a …

A toroidal dipole is a new class of electromagnetic excitations and are different from
traditional electric and magnetic dipoles. Toroidal dipoles are described by the poloidal …

A silicon metasurface with a symmetry-protected quasi-dark resonant mode is designed and
demonstrated as a refractometric sensor and tunable notch filter in the near-infrared …

An all‐dielectric metasurface exhibiting a strong toroidal resonance is theoretically designed
and experimentally demonstrated as an angular‐dependent resonant polarization beam …
