ABSTRACT: It is proposed to demonstrate a surface fabricated using thin film metamaterial designs that can exhibit rapidly varying angular as well as spectral emissivity profiles. The technology enables specification of desired angular pattern at design time, and can be fabricated in large area formats. BENEFIT: The proposed technology will allow directional control of thermal radiation in applications where omnidirectional thermal radiation patterns are not desirable. This will benefit thermal management challenges of military and civilian satellites. It can also serve to enhance performance of thermal energy conversion technology.
