【摘要】 本文提出一种新的芯板电荷分布形式,并借助格林函数和变分公式,对屏蔽带状线进行了空域分析。对芯板位置任意的一般情形,给出了电容、特性阻抗、电位分布和电场分布的解析表达式;与其他方法比较,其数值结果易于实现,精度较高。本文提出的方法,对偏心或对称的横电磁波传输室(TEM cell)特性分析尤为适用。更多还原

【Abstract】 This paper presents a new form of charge distribution on the inner conductor. By using of the Green’s function/valiational formulation with the new form of charge distribution,a general analysis of shielded strip line in the space domain is carried out.Expressions for the capacitance,characteristic impedance,potential distribution and electric field distribution are obtained for any arbitrary location of the inner conductor.The numerical results,which achieve higher accuracy,are easier to derive from present analysis in comparison with previously published li- terature.The method presented in this paper is most suitable to the study of charac- teristics of the TEM cell.更多还原
