Deskripsi
When approaching atomic-scale confinement of the electromagnetic radiation nonlocal effects are not negligible. Here the authors approach that regime, probing extremely confined gap plasmon modes by means of scanning near-field optical microscopy, and suggesting that quantum nonlocal corrections should be taken into account.
