  We review the near-field radiative heat flux between hyperbolic materials
focusing on multilayer hyperbolic meta-materials. We discuss the formation of
the hyperbolic bands, the impact of ordering of the multilayer slabs, as well
as the impact of the first single layer on the heat transfer. Furthermore, we
compare the contribution of surface modes to that of hyperbolic modes. Finally,
we also compare the exact results with predictions from effective medium
theory.
