Abstract
The optical properties of noble metals (Cu, Ag, and Au) have been studied in the mid-infrared using emissivity measurements at 473 K. Their optical responses can be described using classical free-electron expressions in the Mott–Zener approximation with an additional term to account for the extra emission due to the anomalous skin effect, with no free parameters. Clear differences between the specular and diffuse surface scattering regimes can be observed. These results constitute metrological-quality validations of the thermal radiative properties of these important metals.
通过在 473 K 下测量发射率，研究了贵金属（铜、银和金）在中红外的光学特性。它们的光学响应可以使用莫特-齐纳近似中的经典自由电子表达式来描述，该表达式带有一个附加项，用于解释由于反常趋肤效应而产生的额外发射，并且没有自由参数。可以观察到镜面散射和漫反射表面散射状态之间的明显差异。这些结果构成了这些重要金属热辐射特性的计量质量验证。
