Real-Space Mapping of the Strongly Coupled Plasmons of Nanoparticle Dimers

We carried out the near-field optical imaging of isolated and dimerized gold nanocubes to directly investigate the strong coupling between two adjacent nanoparticles. The high-resolution (∼10 nm) local field maps (intensities and phases) of self-assembled nanocube dimers reveal antisymmetric plasmon...
