本文中对任意费米面求出了金属在红外波段的表面电阻,所得表达式适用于各种性质的趋肤效应(正常、反常和中间情况)。发现在反常趋肤效应时,电场的一个分量衰减很慢,它所决定的电磁波等透系数可能比通常已知者大几个数量级。建议利用此效应发展鉴定超纯金属纯度的无接触测量方法。此外,还考虑了有垂直磁场存在时的表面电阻。Surface impedance of metals in infrared region is calculated for an arbitrary Fermi surface. Expressions applicable to all cases of skin-effect (normal, anomalous and intermediate) are obtained. For anomalous skin-effect a component of electric field decreases very slowly in the depth of metals, which leads to the transparency of metallic films. It is proposed to develop a contactless method for the purity control of well refined metals by means of this effect. Surface impedance in a perpendicular magnetic field is also considered.
