title: Cloaking and enhanced scattering of core-shell plasmonic nanowires.
abstract: We study scattering of light from multi-layer plasmonic nanowires and reveal that such structures can demonstrate both enhanced and suppressed scattering regimes. We employ the mode-expansion method and experimental data for material parameters and introduce an optimized core-shell nanowire design which exhibits simultaneously superscattering and cloaking properties at different wavelengths in the visible spectrum.
