In many cases, optical metasurfaces are studied in the single-resonant regime. However, a
multiresonant behavior can enable multiband devices with reduced footprint, and is desired …

Bound states in the continuum (BICs) have been thoroughly investigated due to their
formally divergent Q‐factor, especially those emerging in all‐dielectric, nanostructured …

The bianisotropy of meta-atoms is usually associated with their nonlocal response and
mutual coupling between electric and magnetic dipole moments induced by an incident …

A general strategy for the realization of electric and magnetic quasi‐trapped modes located
at the same spectral position is presented. This strategy's application makes it possible to …

High-index nanoparticles are known to support radiationless states called anapoles, where
dipolar and toroidal moments interfere to inhibit scattering to the far field. In order to exploit …

We comprehensively review the deceptively simple concept of dipole scattering in order to
uncover and resolve all ambiguities and controversies existing in the literature. First, we …

Resonant optical responses of anisotropic molybdenum disulfide (MoS 2) nanoparticles
(NPs) and their two-dimensional arrays (metasurfaces) are investigated. The nanoparticles …

Herein, we discuss the conditions for excitation of symmetry-protected toroidal dipole modes
in all-dielectric metasurfaces composed of trimer or twin-trimer clusters of dielectric disks …

Optical nonreciprocity is manifested as a difference in the transmission of light for the
opposite directions of excitation. Nonreciprocal optics is traditionally realized with relatively …

When light interacts with a material made from subwavelength periodically arranged
constituents, non-local effects can emerge. They occur because of either a complicated …
