近年來核爆脈衝電磁波的電磁場干擾問題及相關研究漸漸受到各個國家的重視,研究中多使用核爆脈衝波模擬器來分析其特性,本論文中我們主要是以束波模擬器為研究方向,建立平行板核爆脈衝波模擬器與線型陣列核爆脈衝波模擬器研究系統中的電磁場,並分別分析了準靜態場與橫向電磁模兩者的特性。主要研究方法含兩種:以時域貫量法研究電場的各種特性;以必歐沙伐定律研究磁場的各種特性。研究結果將報告平行板模擬器內的總電容、總電感及兩種模擬器內電場及磁場的時間響應與其所對應的電場和磁場分佈情形。準靜態場中我們發現在它的有效區域內電磁場並無失真現象;而在橫向電磁波的場形分佈會受到反射係數的影響在波源端和終端有不同的失真效應。從數值分析中可發現在有效區域內電磁場皆均勻分佈;外部則可發現當場點接近模擬器的邊緣時,電磁場的振幅會明顯地增加許多。

In recent years, there has been an increasing interest in the studies of Electromagnetic Interference (EMI) problems due to the interactions with the Nuclear Electromagnetic Pulse (NEMP) waves. Many types of NEMP simulators are used for the analysis of EMI problems. In this thesis, the Time-Domain Moment-Method (TDMM) and the Biot-Savart Law are used for the simulations of electromagnetic field distributions inside the parallel-plate simulator and the wire-array simulator. In the study, we focused on the quasi-static and the TEM-mode conditions. Numerical results of transient electromagnetic fields and electromagnetic field distributions are presented. The characteristic impedance, total capacitance, and total inductance of the parallel-plate simulator are also presented. In the study of the quasi-static condition, it is found that the electromagnetic fields in the working volume appear without any distortion. In analysis of the TEM-mode condition, it is found that the distortion wave form of the electromagnetic fields are greatly affected by the reflection coefficients at both the source and terminating end. From the numerical results, we found that the electromagnetic fields are almost homogeneously distributed inside the working volumes of the parallel-plate simulator and the wire-array simulator. Outside the working volume of these simulators, the electromagnetic fields increase to a maximum value as the field point approaches the source of termination of the simulator.
