We investigate the nonlocal effects on plasmon spectra of cylindrical metallic nanostructures using a semiclassical nonlocal hydrodynamic description of the electron density. We obtain new dispersion relations for plasmon modes in nanowires, nanocavities, nanotubes, and parallel nanowires and compare the results with recent works based on the purely classical local-response Drude model.We find that the nonlocal effects lead to a significantly modified plasmon dispersion relations of the systems.
