WebSep 7, 2024 · Reflectance and conductivity. 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 … WebTungsten-Copper Heat Sinks. They are composites of tungsten and copper.
