We introduce a many body theory for thermal far-field emission of dipolardielectric and metallic nanoparticles in the vicinity of a substrate within theframework of fluctuational electrodynamics. Our theoretical model includes thepossibility to define the temperatures of each nanoparticle, the substratetemperature, and the temperature of the background thermal radiation,separately. To demonstrate the versatility of our method, we apply it in anexemplary way by discussing the thermal radiation of four particle assembliesof SiC and Ag nanoparticles above a planar SiC and Ag substrate. Furthermore,we use discrete dipole approximation to determine the thermal emission of aspherical nanoparticle in free space and close to a substrate. Finally, thecalculation of the thermal far-field radiation of a sharp Si tip close to a SiCsubstrate using the discrete dipole approximation including the near-fieldscattering by the tip as well as the thermal emission of the tip and thecontribution of the substrate which is partially blocked by the tip serves asanother example.
