摘要: 信号传输线的趋肤效应直接影响传输性能.通常引用半无限大导体对入射电磁波的衰减规律来定性说明传输线上的趋肤效应.本文则根据麦克斯韦方程组对导线内的电流分布进行分析,得出了导线内电流存在趋肤效应的结论,并推导了孤立圆导线单位长度的电阻计算公式.
关键词: 趋肤效应, 信号传输线, 麦克斯韦方程, 交流电阻
Abstract: The skin effect directly affects the transmission properties of wire, the attenuation pattern of electromagnetic wave in half unlimited conductor is usually used to describe the skin effect in wire, the qualitative description directly. This paper analyses the distribution of electric current in wire by solving the Maxwell equation and reaches a conclusion that there is skin effect in wire, and deduce the formula to calculate the AC resistance of isolated wire.
Key words: skin effect, transmission line for signals, Maxwell equation, AC resistance
