Gold nanorod heptamers. (a) Schematic showing the splitting of doubly degenerate modes in circular heptamer to azimuthal and radial modes in nanorod heptamer. The white colored arrows represent the radial modes and gold colored arrows represent azimuthal modes. Simulated extinction spectra for (a) azimuthal and (b) radial nanorod heptamers for the same structural parameters: individual nanorods have a length of 95 nm, width of 50 nm and thickness of 40 nm. The center particle has a diameter of 147 nm and gold thickness of 40 nm. The gaps between the center particle and the nanorods are 22 nm. (From Ref. [22])
