Abstract
The coupling of plasmonic nanoparticles can
strongly modify their optical properties. Here, we show that the
coupling of the edges within a single rectangular particle leads to
mode splitting and the formation of bonding and antibonding edge
modes. We are able to unambiguously designate the modes due to
the high spatial resolution of electron microscopy-based electron
energy loss spectroscopy and the comparison with numerical
simulations. Our results provide simple guidelines for for the
interpretation and the design of plasmonic mode spectra.
