Fig. 6.6 a A SEM image of the triangular gold mesoplate (edge length ~810 nm, thickness ~30 nm).
b Near-field extinction spectrum taken at the red point in (a). c Relation between the experimental
resonance energy and the calculated eigenenergy. E 0 is the eigenenergy of the lowest eigenmode.
d–f Near-field transmission images of the mesoplate. Observation wavelength: ~740 nm for (d),
~800 nm for (e), and ~880 nm for (f). White dotted lines represent the approximate shapes of the
mesoplate. Scale bars: 200 nm. g–i Square moduli of the calculated eigenfunctions. Eigenenergy:
12.33E 0 for (g), 9E 0 for (h), and 6.33E 0 for (i). The irreducible representations are shown for each
eigenfunction. Reprinted with permission from [60]. Copyright 2018 American Chemical Society
