Inspired by its fractal structure, this paper studies the potential application of these self-similarity fractal structures to create a plasmonic nano-antenna that can operate over a large linewidth. These devices are studied both theoretically and experimentally. It is shown that these nano-antennas can produce electric field enhancements above 8 over 200nm range and surface enhanced Raman scattering (SERS) enhancements higher than 105.Keywords: Electric field enhancement; Fractal structures; Nano antennas; Self-similarities; Surface enhanced Raman Scattering (SERS); Surface plasmons; Electric fields; Fractals; Integrated optics; Plasmons; Raman scattering; Surface scattering; Antennas Integrated optics; Plasmonic nano-antenna; Surface enhanced Raman scattering; Surface plasmons201310.1080/09500340.2013.8130892016-02-24
