From theoretical model to experimental realization, the bound state in the continuum (BIC) is
an emerging area of research interest in the last decade. In the initial years, well-established …

Control over the dispersion of the refractive index is essential to the performance of most
modern optical systems. These range from laboratory microscopes to optical fibres and even …

Rapid progress in photonics and nanotechnology brings many examples of resonant optical
phenomena associated with the physics of Fano resonances, with applications in optical …

BACKGROUND Nanoscale optics is usually associated with plasmonic structures made of
metals such as gold or silver. However, plasmonics suffers from high losses of metals …

High-index dielectric and semiconductor nanoparticles supporting strong electric and
magnetic resonances have drawn significant attention in recent years. However, until now …

Metasurfaces have become a rapidly growing field of research in recent years due to their
exceptional abilities in light manipulation and versatility in ultrathin optical applications. They …

The original Kerker effect was introduced for a hypothetical magnetic sphere, and initially it
did not attract much attention due to a lack of magnetic materials required. Rejuvenated by …

Monolayer transition metal dichalcogenides (TMDCs) have recently been proposed as an
excitonic platform for advanced optical and electronic functionalities,–. However, in spite of …

Abstract Two-dimensional (2D) transition metal dichalcogenide (TMDC) materials, such as
MoS 2, WS 2, MoSe 2, and WSe 2, have received extensive attention in the past decade due …

The numerical aperture (NA) of a lens determines its ability to focus light and its resolving
capability. Having a large NA is a very desirable quality for applications requiring small light …
