Numerical Simulation of Electron Energy Loss Spectroscopy of Aluminum Nanodisk Surface Plasmons

We perform simulations to model electron energy loss spectroscopy of aluminum nanodisk surface plasmons. Nanodisk geometry and e-beam position determine excitation and energy of plasmonic modes. Multipolar modes are explained with a circulating waveguide model.
