FREE-DOWNLOADT Kosako, Y Kadoya… – Nat. Photonics, 2010 –
The plasmon resonance of metal nanoparticles can direct light from optical emitters in much
the same way that radio- frequency antennas direct the emission from electrical circuits.
Recently, rapid progress has been made in the realization of single-element antennas for
