Fig. 1.17 Spatial distributions of the local optical field intensities at the surface of the metal nanostructure. Panels a–h correspond to the excitation with pulses A–H. Each such a distribution is
displayed for the instance t at which the intensity for a given panel reaches its global maximum in
space and time. This time t is displayed at the top of the corresponding panels. The corresponding
targeted sites are indicated by arrows and labeled by the corresponding letters A–H and the coordinates (x, z). No special normalization has been applied so the distribution within any given panel
is informative but not necessarily the magnitudes of the intensities between the panels
