Surface characteristics of metals and waveguide attenuation at millimeter-wave frequencies between 25 and 180 GHz
Abstract
Discrepancies between theoretical and experimental values of the surface resistance of metals were studied, using plane and rough copper surfaces. One set of experiments sought to separate the causes of the excess losses responsible for the discrepancies and to ascertain an intrinsic value of the surface resistance of conductors. The effect of artificially created surface roughness on surface resistance was determined, and precision measurements of commercially available wave guides were obtained. The anomalous skin effect of single-crystal copper was investigated by measuring the Q-factor of a rectangular cavity in which the plane surfaces to be investigated formed the side walls.
