Surface plasmon polaritons, as a surface electromagnetic wave, have plenty of features in the near-field zone. We find that not only localized SSPs but also magnetic plasmon resonance play a vital role in plasmonic electromagnetically induced transparency (EIT). Their interaction is investigated in detail by analyzing the phase evolution of the induced electromagnetic fields in nanoscale volume, which is rendered by the unique near-field properties and not the case in the far-field zone. Based on this picture, the plasmonic EIT controlled by a single optical field is suggested in a modified scheme for active plasmonic switching by simply adjusting the incident angle of the optical field. The tunability of plasmonic EIT in this scheme is exhibited sufficiently.
