Near-field radiative heat transfer (NFRHT) in nanoparticle networks iscomplicated due to the multiple scattering of thermally excited electromagneticwave (namely, many-body interaction, MBI). The MBI regime is analyzed using themany-body radiative heat transfer theory at the particle scale for networks ofa few nanoparticles. Effect of MBI on radiative heat diffusion in networks of alarge number of nanoparticles is analyzed using the normal-diffusion radiativeheat transfer theory at the continuum scale. An influencing factor $\psi$ isdefined to numerically figure out the border of the different many-bodyinteraction regimes. The whole space near the two nanoparticles can be dividedinto four zones, non-MBI zone, enhancement zone, inhibition zone and forbiddenzone, respectively. Enhancement zone is relatively smaller than the inhibitionzone, so many particles can lie in the inhibiting zone that the inhibitioneffect of many-body interaction on NFRHT in nanoparticle networks is common inliterature. Analysis on the radiative thermal energy confirms that multiplescattering caused by the inserted scatter accounts for the enhancement andinhibition of NFRHT. By arranging the nanoparticle network in aspect ofstructures and optical properties, the MBI can be used to modulate radiativeheat diffusion characterized by the radiative effective thermal conductivity($k_{\rm eff}$) over a wide range, from inhibition (over 55% reduction) toamplification (30 times of magnitude). To achieve a notable MBI, it isnecessary to introduce particles that have resonances well-matched with thoseof the particles of interest, irrespective of their match with the Planckianwindow. This work may help for the understanding of the thermal radiation innanoparticle networks.
