Nonradiating current configurations have been drawing the attention of the physics community for many years. It has been demonstrated recently that dielectric nanoparticles provide a unique platform to host such nonradiating modes, called “anapoles

Optical metasurfaces consist of a 2D arrangement of scatterers, and they control the amplitude, phase, and polarization of an incidence field on demand. Optical metasurfaces are the cornerstone for a future generation of flat optical devices in a wid

There is an ever-growing need to study the optical response of complex photonic systems involving multi-scattering phenomena with strong near-field interactions. Since fully numerical methods often imply high computational costs, semi-analytical meth

We study the near-field enhancement of oligomers composed of high-refractive-index spherical particles. The huge enhancement of the electromagnetic field in the gap between the particles is observed. We reveal that this phenomenon is associated with

Scattering of a corrugated plane wave (cpw) by a sphere is formulated by a pair-of-waves (pow) approach, whereby the incident wavefront is considered as a continuum of sinusoidal wavefronts and any such constituent is considered as a pair of equal-am
