Towards a black body for near-field thermal radiation    [PDF]

We study the near-field heat exchange between hyperbolic materials and
demonstrate that these media are able to support broadband frustrated modes
which transport heat by photon tunnelling with a high efficiency close to the
theoretical limit. We predict that hyperbolic materials can be designed to be
perfect thermal emitters at nanoscale and derive the near-field analog of the
blackbody limit.
