Abstract

In one aspect, the present invention provides a radiation-absorbing structure, which includes a metallic layer and a plurality of protuberances formed in the metallic layer. The protuberances are configured to selectively enhance radiation absorptance at wavelengths less than a cut-off wavelength, for example, for incident radiation wavelengths less than about 2500 nm (2.5 microns), hi some cases, the cut-off wavelength below which the protuberance provide enhanced radiation absorptance can be about 2000 nm or 1800 nm. For example, the protuberances can enhance radiation absorptance for wavelengths in a range of about 300 nm to about 2500 nm, or in a range of about 300 nm to about 2000 nm, or in a range of about 300 nm to about 1800 nm. Further, in many embodiments the radiation absorbing structure exhibits a low emissivity at longer wavelengths, e.g., at wavelengths greater than about 3000 nm.
