Abstract :
Selective thermal emission from metal surfaces can be achieved through wavelength-scale patterning of the substrate. Here we demonstrate mid-infrared selective thermal emission from periodically patterned steel surfaces with selective emission enhancement at the selected wavelength of a factor of 2.6. This phenomenon is numerically modeled and the emission is characterized with Fourier transform infrared spectroscopy.
