Figure 7From: Optical interactions in plasmonic nanostructures Plasmon coupling in nanorod dimer. (a) Schematic drawings of a coupled-dipole nanoantenna made of two plasmonic nanorods with a small gap and its mechanical analog, a coupled mechanical oscillator. (b) Energy-level diagram and simulated near-field intensity spectra for 30Â nm high, 50Â nm wide and 110Â nm long symmetric two-nanorod antennas with 6Â nm (blue dashed) and 16Â nm (green solid) gap, as well as single-nanorod antennas with the same dimensions (black dotted) (From Ref. [90]). Plasmon coupling in nanorod dimer.
