Spectral Imaging of Individual Split-Ring Resonators [PDF]
Physical Review Letters, 2010 We report on spectral imaging within individual silver split-ring resonators (SRRs) operating in the near infrared-visible range. We classified the optical eigenmodes from the measurement of their energies and nanometer scale spatial distributions. They are plasmonic standing waves that show great similarities with that of nanoantennas.

Tunable Resonances in the Plasmonic Split-Ring Resonator
IEEE Photonics Journal, 2014 A nanoscale resonator composed of two metal-insulator-metal (MIM) waveguides and a split ring is investigated numerically. The multipolar plasmonic resonance modes can be excited, weakened, or even cut off by adjusting the split angle. These novel phenomena are due to the electric polarization in the split area.
