Plasmonic Modes and Optical Properties of Gold and Silver Ellipsoidal Nanoparticles by the Discrete Dipole Approximation

Figure 2

The normalized absorption spectra as a function of the incident wavelength for (a) Au and (b) Ag ellipsoidal nanoparticle. In both cases, the principal axis of the particle is aligned parallel to the incident electric field. The corresponding structural parameters are 2a = 40 nm, 2b = 20 nm, and 2c = 10 nm.
