We report on the influence of a nanocrystalline diamond (NCD) thin film or its segments on optical response of gold plasmonic single and dimer antennas in the visible and nearinfrared. We have simulated optical response of these
antennas to the electromagnetic radiation in the wavelength range 500–1500 nm. As the response, we take the localized plasmon resonant wavelength and electric field enhancement around the antennas, localized on the top of NCD films or close to NCD segments.Compared to the antennas on a bare glass substrate, the presence of NCD near the antennas causes a significant red-shift of the antenna resonant wavelength and slightly decreases the antenna resonant
scattering cross section. As for the antenna near-field, it is more enhanced at the antenna–NCD interface than at the
antenna–glass one; however, this field is more confined to the interface.
