Abstract
The frequency-and-field dependence of the impedance, its resistive and reactive components, of tungsten and cadmium plates were studied experimentally over the 2−7 MHz frequency range under antisymmetric excitation, with the depth δ of the skin layer close to or larger than the plate thickness d. Here the behavior of the experimental curves is shown to follow closely a relation based on the assumption that most of the impedance is due to the skin effect. A comparison of experimental and theoretical results yields an estimate of the mean free path length for electrons in metals.
