Hattori, Haroldo TLi, Ziyuan2016-04-042016-04-041094-4087http://hdl.handle.net/1885/100942In recent years, plasmonic nano-antennas have been used in a wide range of applications in sensing, particle detection, imaging and Surface Enhanced Raman Scattering (SERS) detection. Also, arrays of nano-antennas have been recently developed to produce more directional radiation beams or to operate over a wide range of wavelengths. In this article, it is shown that small arrays of nano-antennas can be created by recycling the power that flows through their antenna gaps.The authors gratefully acknowledge the financial support of the Australian Research Council (ARC).
