CONTRIBUTIONS TO IRREGULAR BOUNDARY PROBLEMS

摘要: 本文根據(jù)明晰的物理概念,提出了求解具有不規(guī)則邊界傳輸線特性阻抗的區(qū)域分解法。實際上,這是將不規(guī)則邊界問題的求解工程化,也就是把不規(guī)則邊界問題分解為比較規(guī)則圖形的邊界問題來處理。為了說明方法的具體運用,文中分析了特殊截面?zhèn)鬏斁€問題,并通過與文獻中的結(jié)果比較和理論分析,以證實其準確性和實用性。

Abstract: A method is presented for a practical solution of irregular boundary problems. In this method, the irregular boundary is treated as a combination of several simple boundary value problems, which can be solved easily and exactly. To illustrate the application of the method, the characteristic inpedances of some transmission lines with special cross-section are computed. The accuracy of the method is confirmed by comparing the values obtained here with those reported in the literature. -
