The metallic reflectance can be related to the conductivity by the Hagens-Ruben equation (Equation \ref{5}), where ν is the light frequency, ε 0 is the vacuum permitivity (8.85 x 10-12 F/m), and σ is the conductivity. In the infrared region (small frequencies), this equation shows that metals with high reflectance also are …
