DATA REPOSITORY FOR "SELECTION RULES FOR STRUCTURED LIGHT IN NANOOLIOGMERS AND OTHER NANOSTRUCTURES" The data repository contains simulated absorption and scattering spectra of plasmonic nanooligomers. The simulations were performed with the finit difference time domain technique to solve Maxwell's equations. Details on the oligomers and the simulations: The plasmonic oligomers were contstructed from gold discs. The discs had a diameter d=100nm and a height h=40nm. We arranged them in highly symmetric oligomers of two (dimer), three (trimer), four (tetramer), five (pentamer), and six (hexamer) discs with a gap a=20nm between adjacent discs. The structure of the oligomers are shown in oligomer.pdf. We numerically calculated the absorption and scattering spectrum using the commercial FDTD software Lumerical. The simulations used the dielectric function of gold as measured by Johnson and Christie [Johnson, P. B. and Christy, R. W., Phys. Rev. B 6, 4370 (1972)], a background dielectric constant outside the metal \epsilon=1.65, and a mesh override region with 2nm cells to discretize the space around the plasmonic oligomer. The polarization of the exciting light was varied between linear, radial, and azimuthal and the absorption and scattering simulated. For excitation with linearly polarized light we used a total-field scattered-field plane wave source. For excitation with radial and azimuthal polarization we used a customized total-field scattered-field source based on a k-space method [Mansuripur, M., Distribution of light at and near the focus of high-numerical-aperture objectives. J. Opt. Soc. Am. A 3, 2086-2093 (1986).]. The method is suited to calculate the field distribution near the focus of high numerical-aperture objectives. We implemented beams radial and azimuthal polarization having a doughnut radius of \approx 700nm at the position of the oligomer. The optical cross sections were recorded with power monitors. The files contain txt data of the excitation energy and the optical coefficient (absorption or scattering). The naming of the files is as follows: Oligomer-Polarization-OpticalCoefficient_vs_Energy.txt, where Oligomer = Monomer (only LinearX), Dimer, Trimer, Tetramer, Pentamer, Hexamer Polarization = LinearX (linear along x axis, see oligomer.pdf for axis definition), LinearY, Radial, Azimuthal Optical = Absorption, Scattering oligmer.pdf - images of the oligomers. The repository also contains the energetic width and the radiative and nonradiative contributions to the width under azimuthal and linear polarization. azimuthal_rad_nonrad_decay.txt - values for the lowest-energy azimuthally polarized plasmon mode: oligomer order (2-6), energetic peak position (in eV), full width at half maximum (meV), nonradiative decay (meV), error of nonradiative decay (meV), radiative decay (meV), and bulk damping (meV) at the energy of the plasmon. linear_rad_nonrad_decay.txt - same as above, but for the lowest-energy linearly polarized plasmon mode.
