Tomography of near-field radiative heat exchange between mesoscopic bodies immersed in a thermal bath
arXiv:2403.10333 · doi:10.1103/PhysRevB.110.125410
Abstract
A tomographic study of near-field radiative heat exchanges between a mesoscopic object and a substrate immersed in a thermal bath is carried out within the theoretical framework of fluctuational electrodynamics. By using the discrete-dipole-approximation method, we compute the power density distribution for radiative exchanges and highlight the major role played by many-body interactions in these transfers. Additionally, we emphasize the close relationship between power distribution and eigenmodes within the solid paving the way to applications for hot-spot targeting at deep sub-wavelength scale by shape optimization.
