Abstract: Enhancing photon tunneling probability is the key to increasing the near-field radiative heat transfer between two objects. It has been shown that hexagonal boron nitride (hBN) and graphene heterostructures can enable ...

Abstract: Spectral and directional control of thermal emission is critically important for applications such as space cooling and energy harvesting. The effect of magnetic polaritons (MPs) on spectral modulation has been analyzed ...

Abstract: Thermophotovoltaic (TPV) systems are very promising for waste heat recovery. This work analyzes the performance of a nearfield TPV device with a gold reflecting layer on the backside of the cell. The radiative transfer ...

Abstract: This work addresses the validity of the local effective medium theory (EMT) in predicting the nearfield radiative heat transfer between multilayered metamaterials, separated by a vacuum gap. Doped silicon and germanium are ...

Abstract: The present study considers the directional and spectral radiative properties of vertically aligned, heavily doped silicon nanowires for applications as broadband infrared diffuse absorbers. The nanowire array is modeled ...

Abstract: Near-field thermophotovoltaic (NFTPV) devices have received much attention lately as an alternative energy harvesting system, whereby a heated emitter exchanges super-Planckian thermal radiation with a photovoltaic (PV) ...
