A computational study of the interaction of light with silver nanowires of different eccentricity

Two silver nanowires with elliptical cross-section and different surface to surface distances d interact with linearly (y-)polarized light leading to different near-field patterns as shown in the pictogram. In the case of ellipses with major axes along the polarization axis, complex optical spectra arise with size and position varying resonance peaks, and a noticeable enhancement of the scattering cross-sections.
