This National Science Foundation (NSF) Project Grant award, made under the Engineering program (CFDA 47.041), provides $3,000,000 to Vanderbilt University to conduct research on demonstrating "super-Planckian far field radiation" mediated by thermally launched non-equilibrium phonon polaritons. The key objectives are to: (1) demonstrate super-Planckian far field radiation from individual polar nanowires with a gold coating, (2) disclose the polariton launching mechanism and efficiency from the gold coating cavity, and (3) construct large metal surfaces with partially embedded polar nanowire arrays to characterize their emissivity and cooling effectiveness when attached to solar panels and light-emitting diodes. This research aims to establish a new paradigm of far-field radiation that can exceed the Blackbody limit, leading to revolutionary advances in radiative cooling for various engineering applications. The 3-year award period runs from September 1, 2024 to August 31, 2027. No sub-awards are planned under this grant.
