Original Abstract

Electron energy loss spectroscopy is often utilized to characterize localized surface plasmon modes supported by plasmonic antennas. However, the spectral resolution of this technique is rather mediocre. We address this issue by employing the spectral and spatial distribution of the loss probability simultaneously. We propose several spatio-spectral metrics and demonstrate their ability to resolve nearly degenerate modes supported by a dimer of plasmonic discs.
