extensively studied in the context of metamaterials design and applications, in particular as …

The influence of increasing the core size of Ag–Si core–shell nanoparticles has been
investigated by using the values of the linear polarization degree at a right-angle scattering …

We study the effect of contaminants on the resonances of silicon nanoparticles (NPs) by
considering the spectral evolution of the degree of linear polarization of light scattered at …

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 …
