摘要: We analyze the radiative power emitted by a semi-infinite medium and absorbed flat film located in its vicinity. In near-field regime, if is thin enough, surface waves at rear interface of can contribute to heat transfer. As result, be enhanced farther from front surface. near-to-far field transition temporal coherence thermal radiation associated interferences used shape spectrum transferred flux selecting approriate geometrical parameters. These results highlight possibilities control both location where spectral distribution, which are paramount importance for applications such as thermophotovoltaics.
