摘要

本文提出了一種分析方法能夠快速而精確的分析表面波解，用於處理具有介電填充槽的縱向皺褶桿的同軸迴旋腔管。使用ACBC-漸近皺褶邊界條件，能夠從特徵矩陣之中求解，迅速簡潔的獲得頻率和波數之間的色散關係，且獲得場分佈。經由ACBC分析的色散與場分佈的結果將通過商用全波模擬軟體CST進行驗證，並研究改變不同參數對於導體損耗的影響。

In this thesis, we propose an analytical method that provides quick and accurate surface-wave solutions for solving coaxial-cavity gyrotron with a longitudinally corrugated insert which has dielectric-filled grooves. Using ACBC- the asymptotic corrugated boundary condition, it is quite simple and briefly to obtain not only the dispersion relation between the frequency and wavenumber but the field distribution from the solution of the characteristic matrix. Results of dispersion and field distributions generated by ACBC analysis are validated with CST which is a commercial full-wave simulation software. Results of conductor losses with various parameter studies are also reported.
