摘要 针对传统磁准静态方法无法进行高频段邻近效应分析的缺陷,提出一种可适用于横电磁波下整个频段的矩形有损传输线邻近效应分析方法,并推导了邻近效应影响下的交流阻抗,进而对电报方程的阻抗参数进行修正,为宽频信号传输特性分析提供了新思路.仿真结果表明,该分析方法在电流分布和交流电阻的计算上均有较高精度. The classical magneto quasi-static methods can not be applied in proximity effect analysis in high frequency. To solve the problem, a method used to analyze the proximity effect in rectangular loss transmission line is proposed and applied in full transverse electromagnetic （TEM） frequency. Additionally, alternating current （AC） resistances are calculated to correct the parameters in telegraphist＇s equation, so it is feasible to do transmission characteristics analysis in wide band. Simulations show that this method has a good precision in currents distribution and AC resistance calculation.
