Abstract:

Near-field effect can greatly enhance the radiative heat transfer, by taking advantage of surface resonances. In this paper, we present a numerical approach to use coupled-mode theory for the analysis of near-field radiation. We show that by matching the resonant modes on two objects, the near-field radiation can be maximized. The principle can be applied to the designing of different thermal radiation devices, such as thermophotovoltaic (TPV), thermoradiative (TR), and negative electroluminescent (EL) cooling devices.
