论文摘要
对于在高频和低温下具有较大平均自由路径的正常导电膜的射频应用（RF）应用，异常的皮肤效应与正常皮肤效应有很大不同，并且在膜中呈指数型。从膜中的电流和电场（E场）之间的关系开始，计算了沿膜深度的E场的振幅，发现是非单调的。发现表面阻抗在某些薄膜厚度下具有最小值。我们将此计算应用于加速器中用于减少欧姆功率损耗的Cu涂层的S.S.光束管，以确定应施加的最小厚度。
For the radiofrequency (RF) applications of normal conducting film with large mean free path at high frequency and low temperature, the anomalous skin effect differs considerably from the normal skin effect with field decaying exponentially in the film. Starting from the relationship between the current and the electric field (E field) in the film, the amplitude of E field along the film depth is calculated, and is found to be non-monotonic. The surface impedance is found to have a minimum value at certain film thickness. We apply this calculation into a Cu coated S.S. beam pipe used in an accelerator to reduce the ohmic power loss to determine the minimum thickness that should be applied.
