Fano-like interference of plasmon resonances at a single rod-shaped nanoantenna
Fano-like interference of plasmon resonances at a single rod-shaped nanoantenna
Single metallic nanorods acting as half-wave antennas in the optical range exhibit an asymmetric, multi-resonant scattering spectrum that strongly depends on both their length and dielectric properties. Here we show that such spectral features can be easily understood in terms of Fano-like interference between adjacent plasmon resonances. On the basis …
