Figure 3

(a) Extinction spectrum and (b) electric field intensity spectrum at the point A (see Figure 1) for an asymmetric Au nanocross (120, 80) normally illuminated by a polarized plane wave. (c, d) Extinction spectra of the Au nanocross (120, 80) with a polarization along the (c) - and (d) -axis. The electric field distributions ( ) of the plasmon resonance modes (i–iv) are shown on the right.
