Abstract: | A novel thermal source comprising a semiconductor hyperbolic metamaterial
provides control of the emission spectrum and the angular emission
pattern. These properties arise because of epsilon-near-zero conditions
in the semiconductor hyperbolic metamaterial. In particular, the thermal
emission is dominated by the epsilon-near-zero effect in the doped
quantum wells composing the semiconductor hyperbolic metamaterial.
Furthermore, different properties are observed for s and p polarizations,
following the characteristics of the strong anisotropy of hyperbolic
metamaterials. |
