首次提出了一种新型传输线-椭圆锥同轴线,假设其工作模式是TEM模,在球锥面坐标系下分离变量再通过坐标变换成二维平面坐标,并利用图形逼近和取尺寸上下限的几何均值方法计算此种传输线的特性阻抗。
For the first time, a new type of transmission line - elliptical concentric coaxial line is proposed for the first time. Assuming that its working mode is TEM mode, the variables are separated in spherical coordinate system and transformed into two-dimensional plane coordinates by coordinate transformation. The geometric mean method to calculate the characteristic impedance of this transmission line.
