Numerical Study of Plasmonic Efficiency of Gold Nanostripes for Molecule Detection

Figure 5

Evolution of (a) the mean electric amplitude as function of the number of gap and for four distance from the glass surface. Evolution of (b) the integrated electric amplitude density per volume as function of the number of gap. A maximum efficiency is reached at nine gaps (i.e., for ten nanostripes).
