David Rossouw, current PhD student in Botton's group observed the lowest excitation modes at the highest spatial resolution ever reported in plasmonic nanomaterials using electron energy loss spectroscopy. He used the high resolution electron microscopes at the Canadian Centre for Electron Microscopy to measure the spatial distribution of excitation modes in plasmonic waveguides and observe new phenomena of light propagation in Ag nanostructures around sharp bends and kinks.

Very appropriately for Canada, some of the nanostructures used to demonstrate these effects have the shape of ice hockey sticks!
