摘要
场线耦合模型的研究是电磁兼容分析和电磁效应评估的重要组成部分。低频时,可以使用基于准TEM波近似的经典场线耦合模型来计算外场激励下的传输线沿线电流电压响应,然而,当入射波频率增加到对应波长与传输线横向尺寸可比拟时,经典模型将产生不可接受的模型误差,因而需要发展高频情况下的场线耦合模型。介绍了国内外多导体传输线高频场线耦合模型的研究进展,详细分析和比较了两个主流分支:TRI模型和TLST模型;之后简要介绍了传输线超理论TLST模型并以算例说明了该模型的准确性和有效性;最后对高频场线耦合模型的研究内容和研究目标进行了总结和展望。
Abstract
Field-to-line coupling model research is an important part of electromagnetic compatibility analysis and electromagnetic effects assessment. At low frequency, the classical field-to-line model based on quasi-TEM wave approximation can be used to calculate the current and voltage response excited by the external field. However, if the incident frequency becomes high enough that the corresponding wavelength is comparable to the transverse size of the transmission line, the classical model will produce unacceptable model error. Therefore it is necessary to develop high-frequency field-to-line coupling model.This paper introduces the research progress of high-frequency field-to-line coupling models for multi-conductor transmission line. A detailed analysis and comparison of TRI model and TLST model (two main branches of high-frequency field-to-line coupling model) are given.Then the principle of the TLST model is briefly introduced and the model’s validity and accuracy are illustrated by a simulation example. Finally, the research contents and objectives of high-frequency field-to-line coupling model are summarized and prospected.
