Near-Field Heat Transfer between Multilayer Hyperbolic Metamaterials
نویسنده
چکیده
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.

Effectiveness of thin films in lieu of hyperbolic metamaterials in the near field.
We show that the near-field functionality of hyperbolic metamaterials (HMM), typically proposed for increasing the photonic local density of states (LDOS), can be achieved with thin metal films. Although HMMs have an infinite density of internally propagating plane-wave states, the external coupling to nearby emitters is severely restricted. We show analytically that properly designed thin film...
متن کاملBroadband near-field radiative thermal emitter/absorber based on hyperbolic metamaterials: Direct numerical simulation by the Wiener chaos expansion method
In the near field, radiative heat transfer can exceed the prediction from Planck's law by several orders of magnitude, when the interacting materials support surface polaritons in the infrared range. However, if the emitter and absorber are made from two different materials, which support surface polariton resonances at different frequencies, the mismatch between surface polariton resonance fre...
متن کاملHyperbolic metamaterials as an analog of a blackbody in the near field.
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 tunneling 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 an upper limit for the heat flux due to hyperb...
متن کاملNear-infrared surface plasmon polariton dispersion control with hyperbolic metamaterials.
We demonstrate experimentally signatures and dispersion control of surface plasmon polaritons from 1 to 1.8 µm using periodic multilayer metallo-dielectric hyperbolic metamaterials. The fabricated structures are comprised of smooth films with very low metal filling factor. The measured dispersion properties of these hyperbolic metamaterials agree well with calculations using transfer matrix, fi...
متن کاملNear-field Radiative Heat Transfer between Graphene-covered Anisotropic Magneto-dielectric Hyperbolic Materials
The near-field radiative heat transfer (NFRHT) between the anisotropic magneto-dielectric hyperbolic materials (AMDHMs) substrates covered by a monolayer of graphene is theoretically investigated on the basis of the fluctuational dissipation theorem through the scattering method. Unlike that the NFRHT flux between SiC nanowires can be enhanced by graphene coverage, graphene coverages can weakly...
