The field of optical nanoantennas has recently experienced an extensive growth in researchactivities, owing to the fascinating possibility of confining electromagnetic radiation to subwavelengthspatial domains via surface plasmon polaritons. As a result of nanoconfinements,the local electromagnetic field can be significantly enhanced, leading to a number of extraordinaryeffects. The potential of these devices is spectacular; applications range from plasmonicwaveguides and nano-interconnects for ultrafast communications, to solar-cells energy-efficientguiding, biosensors, amplification of molecular responses, increased Raman scattering, andmedical cancer treatments, among others.
