Measurements of the Surface Resistance and the Effective Conductivity of Copper Cladded Laminates Employing Dielectric Resonator Technique

摘要

Dielectric resonator technique has been proposed for precise measurements of the effective conductivity of the inner and the outer surface of copper cladding of microwave laminates. Experiments have shown that the effective conductivity of the inner metal surface is about 4 times smaller than the effective conductivity of the outer metal surface for copper-cladded RT/Duroid.
