The vivid optical properties of noble metal nanoparticles have been an object of fascination
since ancient times. The ruby red of stained glass windows arises from gold nanoparticles …

When light interacts with a metal nanoparticle (NP), its conduction electrons can be driven
by the incident electric field in collective oscillations known as localized surface plasmon …

An ideal surface-enhanced Raman scattering (SERS) nanostructure for sensing and
imaging applications should induce a high signal enhancement, generate a reproducible …

Nanoantennas for visible and infrared radiation can strongly enhance the interaction of light
with nanoscale matter by their ability to efficiently link propagating and spatially localized …

We study in detail a novel type of optical nanoantennas made of high-permittivity low-loss
dielectric particles. In addition to the electric resonances, the dielectric particles exhibit very …

Clusters of plasmonic nanoparticles and nanostructures support Fano resonances. Here we
show that this spectral feature, produced by the interference between bright and dark modes …

Plasmonic clusters can support Fano resonances, where the line shape characteristics are
controlled by cluster geometry. Here we show that clusters with a hemicircular central disk …

The field of optical nanoantennas, a rapidly developing area of optics, is reviewed. The
basic concept of an optical antenna is formulated and major characteristics relevant to this …

Electromagnetic coupling between plasmon resonant nanoparticles follows principles of
molecular hybridization, that is, particle plasmons hybridize to form a lower energy bonding …

Recently, a large number of experimental and theoretical works have revealed a variety of
plasmonic nanostructures with the capabilities of Fano resonance (FR) generation. Among …
