摘要
文章提出用常数单元边界元法计算椭圆外导体同轴传输线族的重要参数——特性阻抗。为检验边界元法的计算精度 ,边界元法计算了有准确参考值的椭圆外导体 -圆柱内导体、矩形内导体同轴传输线族的特性阻抗。以前从未见报导的椭圆外导体 -正三边形内导体、正方形内导体同轴传输线族的特性阻抗数据也一起给出 ,为工程设计提供可靠的参考数据。
A coaxial transmission line family with elliptical outer conductor is of great importance to electromagnetic engineering.In this paper,the electrostatic field boundary value problem of the coaxial transmision line family is solved by the boundary element method(BEM).The accuracy of the characteristic impedance data obtained by the BEM is conformed by comparing some numerical results reported in the literature.Some characteristic impedance data are first presented,and may be applicable to the design of transmision line engineering.
