a Extinction spectra of Al cylindrical particles with different radius R (20, 30, 40, 50, and 60 nm with a height of 50 nm); b The extracted charge and near-field distributions for the Al cylindrical particle with R = 50 nm when excited at the resonance peak at 234 nm. The distribution patterns indicate the quadrupole mode plasmonic resonance in the deep UV region; c Schematic diagram of the dimer structure and the related definition of the parameters; d The corresponding extinction spectra of the dimer structure under P = 0° and P = 90° polarized light irradiation, and with comparison to that of e the single particles
