The surface modes of interacting NPs, which depend on geometrical parameters
of th system, largely modify the near electromagnetic field. The excitation of a
surface mode, explained by near field fluctuations, gives rise to evanescent
waves, which in turn enhances radiative heat exchange between bodies by
several orders of magnitude. Therefore, we want to study the effect of
geometrical parameters, such as size, shape and distance of NPs on the near
electromagnetic field, and consequently in the radiative heat transfer between
two NPs.
We present a spectral representation formalism in the quasi-static
approximation, to obtain the surface resonances of interacting NPs, which is
applied to study the exact near field between two neighboring spherical NPs,
where full high-multipolar interactions are considered. By use of the fluctuationdissipation
theorem in the the spectral representation formalism, radiative heat
transfer taking as an example a spherical homo dimer. This methodology allows
the identification of the dependence of radiative heat transfer on the coupled
plasmon modes of the system.
