分析傳輸線網絡的電磁耦合問題

現(xiàn)代當微波輻照一個雷達接收機時，將對雷達接收機產生“帶內”干擾但是當入射電
磁脈沖作用于系統(tǒng)中的某一設備時，系統(tǒng)中的其他設備也很可能會受到影響。本文采用傳輸線網絡拓撲模型來表示復雜系統(tǒng)，并運用BLT 方程來分析傳輸線網絡對電磁激勵的響應。最后結合三種典型的系統(tǒng)結構進行了舉例分析。
關鍵詞：BLT 方程；傳輸線網絡；電磁激勵；結點散射矩陣；系統(tǒng)結構
Abstract: Modern electric devices always work in complicated electromagnetic environment. Although some shield measures, when an incident electromagnetic pulse acts on a certain device in the system, other devices may be affected. In this paper, a complicated system is represented by a transmission line network topology model, and its response to the electromagnetic excitement is analyzed using BLT Equation. And this paper gives an example of? three typical system configurations.
Key words: BLT Equation；Transmission Line Network；Electromagnetic Excitement；Node Scattering Matrix； systemic configuration
