Extinction efficiency spectra and local electric field enhancements obtained for all the LSPR maxima. a Extinction efficiency spectra corresponding to the offset of 4 nm along all the Cartesian axes (polarization is fixed along the X axis). The insets are color maps representing the local electric field enhancements obtained for all the LSPR maxima. b Differential scattering cross section in the XZ plane at the LSPR maximum for the same structures and for the concentric nanoshell
