摘要
利用误差函数的拉普拉斯变换 ,对复深度法得出的频域阻抗直接进行拉普拉斯变换 ,获得了考虑土壤影响的架空多导体传输线时域自阻抗和互阻抗简单的表达式。通过与Timotin公式和Pade变换的结果进行比较 。
In this paper, the complex impedance of multiple conductor transmission lines (MTLs) above a lossy soil is extended to operational impedance of time domain directly by means of Laplace transform of Error function. The expression is simpler than Pade's approximation and Timoton expression. Comparison with the result of Pade's approximation and Timotin expression shows that the proposed method is accurate.
