This bachelor thesis deals with an experimental and theoretical research of the plasmonic lightning-rod effect. Electron energy loss spectroscopy has been used to investigate the electromagnetic response of plasmonic antennas and to study the impact of the curvature of their surfaces on the local enhancement of an electromagnetic field. A theoretical background based on interactions of the electromagnetic field and free electrons in metals is provided in the first chapter. Next, experimental and theoretical methods including the fabrication process of plasmonic antennas and inicialization of simulations are introduced. Observed resonances of localised surface plasmons are characterised in the spectral region and their mapping is performed. The calculated loss spectra are compared with the experimental loss spectra and the field enhancemnet due to the curvature of plasmonic antennas is evaluated.
