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

<table>Normalized absorption spectra of a (a) Au and (b) Ag ellipsoid of different <i>a</i>-axis length, (c) the band position of LM versus the length of the <i>a</i>-axis. (d) the band position of LM as a function of the nanoellipsoid effective radius. The <i>b</i>-axis and the <i>c</i>-axis are respectively 10 and 5 nm.</table>
