Long-range Heat and Energy Transfer through Hyperbolic Materials
Résumé
Heat flux exchanged between two hot bodies at subwavelength separation distances can exceed the limit
predicted by the blackbody theory. However, this super-Planckian transfer is restricted to these separation
distances. Here we demonstrate the possible existence of a super-Planckian transfer at arbitrary large separation
distances if the interacting bodies are connected in the near field with weakly dissipating hyperbolic waveguides.
This result opens the way to long-distance transport of near-field thermal energy.
