摘要

本文主要探討電磁脈衝（electromagetic pulse, EMP）耦合至地面架空傳輸線（overhead transmission line）之效應。首先，推導出多導體傳輸線（multiconductor transmission lines）之理論模型，並依此理論模型求得其入射耦合之轉換函數（transfer function）。依此函數，本研究將分析雙導體和多導體傳輸線受EMP入射的情形下，連接不同終端阻抗所產生的耐受效應；另外亦考慮接近效應（proximity effect）對此耦合現象之影響。此研究成果將可提供做為國內EMP防護設計之參考。

The purpose of this study is to examine the effects of EMP coupling on overhead transmission lines. First, a theoretical model of a multiconductor transmission line is derived and used to obtain the transfer function of an EMP coupling transmission line. On the basis of this transfer function, the coupling effects of two-conductor and multiconductor transmission lines are analyzed by varying the incident angle, the termination impedance and the associated dimension. The proximity effect is also discussed.
