Abstract
A structure that provides suppression of reflectance of radiation and thus enhanced emissivity is fabricated with a substrate that supports alternating absorber and spacer layers with interleaved antireflectance coatings formed of thin films of different materials having different indices of refraction. Alternate antireflectance coatings are mirror images of the prior deposited antireflectance coatings.
