Figure 2.

Scattering simulations of an isolated slanted nanorods dimer with same geometrical parameters as in Figure 1. (a) Solid lines are the scattering cross sections (CS) in the three illumination conditions sketched in the insets, while the blue dashed line is the absorption CS corresponding to the blue solid scattering CS. Values are normalized to the geometrical CS. Insets on the left show the E_z fields at peak wavelengths in two cross sections of the structures. Field values are normalized to the impinging light amplitude and saturated to arbitrary values to better evidence their distribution. (b) Scattering far-field patterns at resonant wavelengths. (c) Scattering cross-section spectra for different tilting angles α of the dimers and illumination condition as sketched in the inset (for TM and TE polarized light as indicated by the arrows).
