We investigate the enhanced electric dipole-dipole interaction by surface\nplasmon polaritons (SPPs) supported by the planar metal film waveguide. By\ntaking two nitrogen-vacancy (NV) center electric-dipoles in diamond as an\nexample, both the coupling strength and collective relaxation of two dipoles\nare studied with numerical Green Function method. Compared to the two-dipole\ncoupling on planar surface, metal film provides stronger and tunable coupling\ncoefficients. Enhancement of the interaction between coupled NV center dipoles\ncould have applications in both quantum information and energy transfer\ninvestigation. Our investigation provides a systematical result for\nexperimental applications based on dipole-dipole interaction mediated with SPPs\non planar metal film.\n
