Near-field heat transfer between two closely spaced radiating media can exceed in orders radiation through the interface of a single black body. This effect is caused by exponentially decaying (evanescent) waves which form the photon tunnel between two transparent boundaries. However, in the mid-infrared range it holds when the gap between two media is as small as few tens of nanometers. We propose a new paradigm of the radiation heat transfer which makes possible the strong photon tunneling…

Super-Planckian near-field heat transfer
It is well known that the radiative heat flux exchanged between two hot bodies separated by a distance larger than their thermal wavelengths cannot be larger than the flux exchanged between two
Near-field radiative heat transfer between metamaterial thin films.
It is found that the strength as well as the location of magnetic resonance does not change with film thickness until the film behaves as semi-infinite for the dielectric function chosen in this study.
Near-field thermal radiation between hyperbolic metamaterials: Graphite and carbon nanotubes
The near-field radiative heat transfer for two hyperbolic metamaterials, namely, graphite and vertically aligned carbon nanotubes (CNTs), is investigated. Graphite is a naturally existing uniaxial
Long-distance near-field energy transport via propagating surface waves
Near-field radiative heat transfer (RHT) between two bodies can significantly exceed the far-field limit set by Planck's law due to the evanescent wave tunneling, which typically can only occur when
Magnetic field control of near-field radiative heat transfer and the realization of highly tunable hyperbolic thermal emitters
We present a comprehensive theoretical study of the magnetic field dependence of the near-field radiative heat transfer (NFRHT) between two parallel plates. We show that when the plates are made of
Thermal hyperbolic metamaterials.
This work considers practical phonon-polaritonic metamaterials for thermal engineering in the mid-infrared range and shows that the effect exists in spite of the losses, absorption and finite unit cell size.
Large penetration depth of near-field heat flux in hyperbolic media
We compare super-Planckian thermal radiation between phonon-polaritonic media and hyperbolic metamaterials. In particular, we determine the penetration depth of thermal photons inside the absorbing
Active control of near-field radiative heat transfer via multiple coupling of surface waves with graphene plasmon
Abstract It is known that the surface plasmons (SPs) supported by graphene can be strongly coupled with electric SPs supported by the metamaterial and with symmetric and antisymmetric surface phonon
