Metallic nanostructures now play an important role in many applications. In particular, for the
emerging fields of plasmonics and nanophotonics, the ability to engineer metals on …

Optical antennas are an emerging concept in physical optics. Similar to radiowave and
microwave antennas, their purpose is to convert the energy of free propagating radiation to …

The optical properties of plasmonic dipole and bowtie nanoan-tennas are investigated in
detail using the Green's tensor technique. The influence of the geometrical parameters …

Interest in nanotechnology is driven by the unique and novel properties of nanoscale
materials such as the strong interaction of metal particles with light, caused by localized …

Plasmonic hotspots in single gold nanostars are located at the tips and can be excited
selectively by laser light as evidenced by photoelectron emission microscopy. Selectivity is …

Graphene has been demonstrated to be a promising photodetection material because of its
ultrabroadband optical absorption, compatibility with CMOS technology, and dynamic …

We apply a nanomanipulation technique to assemble pairs of monodispersed octahedral
gold nanocrystals (side length, 150 nm) along their major axes with a varying tip-to-tip …

Pairs of gold elliptical nanoparticles form antennae, resonant in the visible. A dye,
embedded in a dielectric host, coats the antennae; its emission excites plasmon resonances …

Gold nanoantenna arrays composed of paired elliptical cylinders are fabricated and studied
experimentally and numerically. The arrays show far-field spectra resonances in the visible …
