This can be regarded as critical coupling to a nano-plasmonic cavity, or as an extension of the concept of time-reversed laser to the spaser. Light scattering is completely suppressed via impedance matching to the nano-objects, and the energy of incoming wave is fully transferred to surface plasmon oscillations and evanescent electromagnetic fields.
