Near-field radiative heat transfer between general materials and metamaterials
- First Online:
We investigated the near-field radiative heat transfer between general materials and metamaterials. We studied the effects of metamaterial parameters on the radiative heat exchange and used three kinds of natural or artificially-constructed materials such as Al, boron-doped Si and metamaterials as examples. We calculated and analyzed the near-field radiative heat transfer processes between two semi-infinite bodies. The numerical results indicate that the radiative heat exchange between the two different materials may be less or more than the radiative heat exchange between the corresponding identical materials. It was found out to depend on the radiative properties of the materials. The work would provide a valuable reference for the selection of practical materials.
