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: 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 ...
