摘要

摘要: 金屬腔體內(nèi)的場線耦合是電磁兼容領(lǐng)域的一個重要的問題，基于模式匹配及BLT方程理論，該文提出一種計算帶孔陣腔體內(nèi)場線耦合的方法。將外部激勵源對腔體內(nèi)傳輸線的耦合分解為孔腔耦合和場線耦合兩個過程，腔體內(nèi)任意點的場強由模式匹配理論及矩量法計算得到，腔體內(nèi)的場線耦合由Agrawal模型構(gòu)建BLT方程進行計算。與測試數(shù)據(jù)對比得出，模式匹配理論可以準確計算腔體內(nèi)部電磁場。與CST數(shù)值仿真數(shù)據(jù)對比得到，該方法可以準確計算任意入射波激勵下線纜終端負載上的電流響應(yīng)且計算效率高，可用于腔體內(nèi)場線耦合的研究。

Abstract: The field-to-wire coupling in metal enclosure is an important issue in the field of electromagnetic compatibility. In this paper, an efficient and accurate approach is presented to calculate the EMI (ElectroMagnetic Interference) of a complex cable bundle in an enclosure, which involves two methods: mode matching and BLT equation. The issue is divided into the two sub-questions: aperture coupling and field-to-wire coupling, the electromagnetic field in enclosure is calculated by the Mode function and MOM, the EMI of the cables in an enclosure is calculated by Agrawal,s field-to-wire coupling theory and BLT equation. In comparison with measurement data shows that the electromagnetic field in enclosure can be accurately calculated by the mode matching method. The proposed method can also significantly reduce the simulation time and improve the efficiency of simulation compared with CST, which can be used to calculate the field-to-wire coupling in an enclosure.
