Abstract :
We find that the surface resistance of smooth copper exceeds that predicted by classical electromagnetic theory. We have fabricated copper surfaces with controlled roughness and grain size. We will present measurements of the reflectivity of these copper surfaces and compare these results to theoretical predictions for the THz resistance of surfaces.
