Abstract

A Volumetric Method of Moments (V-MoM) based full wave eigenmode analysis technique is introduced to the nanoscale and applied to analyze plasmonic structures (monomer, dimer, and the associated composite dolmen structure). It is shown that the eigenfrequencies and eigenmodes determine the resonant frequencies and quality factors of the plasmonic response. Further, the physical origin of the Fano resonance in the dolmen structure is revealed from both individual component and complete structural behavior.
