Abstract

We investigate the near-field radiative heat transfer between two semi-infinite magneto-dielectric uniaxial anisotropic media (MDUAM). SiC nanowires embedded in metamaterials are used to implement electric and magnetic anisotropy, which leads to the hyperbolic dispersion relation for both TE and TM waves. The results show that the TM and TE waves can support both hyperbolic modes and surface modes and that there exist additional modes contributing to the heat transfer for TE waves. Moreover, the MDUAM exhibit super-Planckian thermal emission at ultra-broad bandwidths. This work paves the way for applying the near-field radiative heat transfer in the area of thermal management and energy harvesting.
