  In this letter, we study the near-field radiative heat transfer between two
metamaterial substrates coated with silicon carbide (SiC) thin films. It is
known that metamaterials can enhance the near-field heat transfer over ordinary
materials due to excitation of magnetic plasmons associated with s
polarization, while strong surface phonon polariton exists for SiC.By careful
tuning of the optical properties of metamaterial it is possible to excite
electrical and magnetic resonance for the metamaterial and surface phonon
polaritons for SiC at different spectral regions, resulting in the enhanced
heat transfer. The effect of the SiC film thickness at different vacuum gaps is
investigated. Results obtained from this study will be beneficial for
application of thin film coatings for energy harvesting.
