As the geometrical feature of a nanostructure approaches the Thomas-Fermi screening length, the electron-level interaction induced nonlocality leads to the longitudinal resonance modes above bulk plasmon resonance frequency. In this work, we investigate the contribution of longitudinal modes to the...
