Abstract

In this study, we demonstrate the use of a Generalized Multipole Technique (GMT) to simulate low-loss Electron Energy Loss Spectroscopy (EELS) spectra of isolated spheriodal nanoparticles. The GMT provides certain properties, such as semi-analytical description of the electromagnetic fields, efficient solution of the underlying electromagnetic model, accurate description of the near field, and flexibility regarding the position and direction of the incident electron beam, that are advantageous for computation of EELS spectra. Within the chapter, we provide a derivation of the electromagnetic model and its connection to EELS spectra, and comprehensive validation of the implemented GMT regarding electromagnetic scattering and EELS.
