摘要

基于Pade近似的拉普拉斯变换数值反演已成为传输线(MTL)网络传导电磁干扰耦合路径时域分析的重要工具。本文基于Haar小波理论，提出了一种新的nrt方法，用于分析具有任意线端和互连网络的耦合不等长传输线。该方法使用由Haar小波理论导出的运算矩阵来评估拉普拉斯变换的图像，比以前基于Pade近似的技术更准确。通过两个不等长MTL网络的算例验证了该方法的有效性。

Transient analysis of unequal length multiconductor transmission lines via Haar wavelets-based numerical inversion of Laplace transform

The numerical inversion of the Laplace transform (NILT) with Pade approximation has been used as an important tool for time domain analysis of conducted EMI coupling paths modeled by transmission line (MTL) networks. In this paper a new NILT based on Haar wavelets theory is presented for the analysis of coupled unequal length transmission line with arbitrary linear terminals and interconnecting networks. The method, which uses an operational matrix derived from the Haar wavelets theory to evaluate the image of the Laplace transform, is more accurate than previous techniques based on the Pade approximation. Two numerical examples of unequal length MTL networks are demonstrated to verify the method validity.
