    "abstract": "We report a numerical investigation of surface plasmon (SP) propagation in\nordered and disordered linear chains of metal nanospheres. In our simulations,\nSPs are excited at one end of a chain by a near-field tip. We then find\nnumerically the SP amplitude as a function of propagation distance. Two types\nof SPs are discovered. The first SP, which we call the ordinary or quasistatic,\nis mediated by short-range, near-field electromagnetic interaction in the\nchain. This excitation is strongly affected by Ohmic losses in the metal and by\ndisorder in the chain. These two effects result in spatial decay of the\nquasistatic SP by means of absorptive and radiative losses, respectively. The\nsecond SP is mediated by longer range, far-field interaction of nanospheres. We\nrefer to this SP as the extraordinary or non-quasistatic. The non-quasistatic\nSP can not be effectively excited by a near-field probe due to the small\nintegral weight of the associated spectral line. Because of that, at small\npropagation distances, this SP is dominated by the quasistatic SP. However, the\nnon-quasistatic SP is affected by Ohmic and radiative losses to a much smaller\nextent than the quasistatic one. Because of that, the non-quasistatic SP\nbecomes dominant sufficiently far from the exciting tip and can propagate with\nlittle further losses of energy to remarkable distances. The unique physical\nproperties of the non-quasistatic SP can be utilized in all-optical integrated\nphotonic systems.",
