RISApplication Conditions of Effective Medium Theory in Near Field Radiative Heat Transfer Between Multilayered Metamaterials
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Wideband Tunable Omnidirectional Infrared Absorbers Based on Doped Silicon Nanowire Arrays
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
A Computational Simulation of Using Tungsten Gratings in Near-Field Thermophotovoltaic Devices
Publisher: The American Society of Mechanical Engineers (ASME)
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) ...
