The recent rise of metamaterials opens new opportunities for absorbers due to their
designed electrodynamic properties and effects, allowing the creation of materials with …

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 …

Metamaterials, man-made composite media structured on a scale much smaller than a
wavelength, offer surprising possibilities for engineering the propagation of waves,,,,,. One of …

Since its discovery, the asymmetric Fano resonance has been a characteristic feature of
interacting quantum systems. The shape of this resonance is distinctively different from that …

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 …

A metallic nanostructure consisting of a disk inside a thin ring supports superradiant and
very narrow subradiant modes. Symmetry breaking in this structure enables a coupling …

Electromagnetic metamaterials (MMs) and metasurfaces (MSs) are artificial media and
surfaces with subwavelength separations of meta-atoms designed for anomalous …

We demonstrate the transition from isolated to collective optical modes in plasmonic
oligomers. Specifically, we investigate the resonant behavior of planar plasmonic hexamers …

We observe the appearance of Fano resonances in the optical response of plasmonic
nanocavities due to the coherent coupling between their superradiant and subradiant …

Plasmonic nanostructures concentrate optical fields into nanoscale volumes,, which is useful
for plasmonic nanolasers,, surface enhanced Raman spectroscopy, and white-light …
