本文建立了关于螺旋皱纹内、外导体同轴电缆特性阻抗不均匀性的理论。从缓变的近似圆截面导体模型出发
利用区域变分法和黎卡迪方程
推导出计算特性阻抗和电压反射系数的近似解析表达式
系统分析了电缆设计、制造和安装等实际问题。
In this paper a theory on the non-uniformity of characteristic impedance of coaxial cables with helical corrugated inner-and outer-conductors is proposed. From a model of conductors with slowly varying quasi-circular section
by means of the domain variational ap-proach and Riccati equation
the approximate analytic expression for calculating the characteristic impedance and the voltage reflection coefficient are derived. Many problems on cable design
manufacture and connection are analysed.
