Radiative heat transfer on microscale enhanced by wire media

Radiative heat transfer on microscale enhanced by wire media

Introducing arrays of carbon nanotubes and metal nanowires into a gap of a micro-thermophotovoltaic system so that the cold and hot nanowires/nanotubes do not intersect one may achieve strongly super-Plankian fluxes of radiative heat and also the high frequency selectivity of this effect when the thermal flux is huge in the narrow frequency band and suppressed beyond it. This effect opens the way to a new generation of thermophotovoltaic systems.
