Abstract: A method for laser-processing a metallic surface to produce a functionalized metallic surface comprises: providing a material substrate having the surface; and applying a pulsed laser beam to a region of the surface, the pulsed laser beam being applied at a non-normal angle to the surface, wherein material in the region of the surface ablates due to the applied pulsed laser beam and wherein at least a portion of the ablated material redeposits on the surface to produce one or more material-coated structures angled at the non-normal angle with respect to the surface, wherein the surface having the one or more material-coated structures is the functionalized surface. The functionalized metallic surface has broadband directional emissivity independent of polarization.
