Beyond Stefan-Boltzmann Law: Thermal Conductivity in Hyperbolic Metamaterials

We demonstrate that the broadband divergence of the photonic
density of states in hyperbolic media leads to giant increase in
radiative heat transfer, beyond the limit set by the Stefan-Boltzmann law. The resulting radiative thermal “hyper-conductivity” may approach  the heat conductivity via electrons and phonons in regular solids.
