AbstractSpatially-resolved low-loss electron energy loss spectroscopy (EELS) is a wellestablished technique for probing optical excitations in nanostructures and with recent instrumental improvements, it can be utilized even in infrared (IR) spectral region. We explore possibilities of IR-EELS for characterizing metallic nanostructures supporting excitations of localized surface plasmons. We present experimental and theoretical results for different antenna geometries and demonstrate that both spectral and spatial information provided by the electron beam is important for an elaborate analysis of such systems.
