In this work we theoretically demonstrate the possibility of cloaking a given object by surrounding it with a finite collection of suitably dimensioned, discrete "antiphase" plasmonic scatterers. It is shown that the total scattering from the object may approximately be canceled by the currents induced on a finite number of the plasmonic "satellite" scatterers, effectively making the whole system invisible to an external observer. Unlike other approaches, the proposed solution allows one to cloak a given object in a noninvasive manner since the antiphase satellites, being finite in number, do not need to fully cover and be in direct contact with the cloaked object.
