A hypothesis of the existence of perfect nonradiating modes in dielectric nanoparticles of an arbitrary shape is put forward. It is strictly mathematically proved that such modes exist in axisymmetric dielectric nanoparticles and have unlimited radia

A general concept of perfect nonradiating modes in dielectric nanoparticles of an arbitrary shape is put forward. It is proved that such modes exist in axisymmetric dielectric nanoparticles and have unlimited radiative Q-factors. With smart tuning of

International audience; A generic model of two dissimilar antenna-type resonators coupled both via near-field and farfield and embedded in active gain and/or loss medium is considered. Conditions required for hitting the superscattering regime corres

The exact analytical solution of Maxwell equations for a Bessel light beam scattered by a sphere is found. Scattered power, stored energy, and a generalized Q factor as a function of frequency, the sphere radius, permittivity, and the Bessel beam ang

The general concept of Fano resonance is considered so as to show the possibility of this resonance in space. Using a recently found solution for a Bessel wave beam impinging on a dielectric sphere, we analyze the electromagnetic fields near a micros

The generic model of two coupled multimode plasmonic nanospheres with gain and loss forming a parity-time $(\mathcal{PT})$ symmetric dimer is considered. Analytical solutions based on a quasistatic approximation are used to explore the behavior of th

It is shown that, depending on the incident wave frequency and the system geometry, the extraordinary transmission of light through a metal film perforated by an array of subwavelength holes can be described by one of the three mechanisms: the “tra
