摘要
本文提出用边界元法计算横电磁波传输室的重要参数——特性阻抗。为检验边界元法的计算精度 ,边界元法分别计算了有解析解的零厚度横电磁波传输室和无解析解的几种常用横电磁波传输室。计算结果表明 :边界元法是计算横电磁波传输室特性阻抗的一种有效方法 ,不仅具有较高的计算精度 。
TEM transmission cell(TTC),consisting of a laminated inner conductor plate and a rectangular hollow outside conductor,is of great importance to electromagnetic engineering.In this paper,the boundary element method (BEM) is presented for computation of the characteristic impedance of the TTC.The accuracy of the impedance data obtained by the BEM is confirmed by comparing some numerical results reported in the literature.By calculating engineering examples,it has been shown that the BEM is an effective approach for computation of the characteristic impedance of the TTC,and is applicable to the exact design of the TTC engineering problems.
