Due to the 'curved anisotropy' of such nano-objects, the interpretation of the EEL spectra is far from being straightforward and an adapted theoretical framework is then required. In this contribution, we extend the continuum dielectric approach to hollow anisotropic cylindrical nanoparticles, showing that the energy-loss probability can be handled both analytically and numerically.
