Nanocrosses with Highly Tunable Double Resonances for Near-Infrared Surface-Enhanced Raman Scattering
(a) Extinction and (b) electric field intensity spectra at the point A (see Figure 1) for a Au nanocross (120, 80) illuminated by a plane wave with different polarizations. The angle (θ) between the light polarization and the -axis is (i) 0, (ii) 15, (iii) 30, (iv) 45, (v) 60, (vi) 75, and (vii) 90 degree.
