"Near-field mapping of three-dimensional surface charge poles for hybridized plasmon modes." <i>AIP Advances,</i> 5, (2015) AIP Publishing LLC: 107221. http://dx.doi.org/10.1063/1.4934722.https://hdl.handle.net/1911/87853We describe a new computational approach to mapping three-dimensional (3D) surface charge poles and thus to determine complicated and hybridized plasmon modes in metallic nanostructures via finite element method (FEM) calculations. 3D surface charge distributions at the near-field resonance energies are calculated directly using Gaussﾒ law. For a nanosphere dimer, we demonstrate that higher-order hybridized plasmon modes can be addressed clearly. As an improvement to conventional mapping approaches, this new approach provides a better understanding of comprehensive physical image of plasmonic systems necessary for fundamental studies and spectroscopy applications.engAll article content, except where otherwise noted, is licensed under a Creative Commons Attribution 3.0 Unported License.Journal articlehttp://dx.doi.org/10.1063/1.4934722
