非对称平行双线中TEM波的求解,可首先通过复数坐标系z上的分式线性变换,由静态场在相同边界条件下得出的电场的解,乘以波动因子得到TEM波的电场解,然后根据由麦克斯韦方程所联系的电场与磁场的关系,得到磁场的分布,再由分式线性变换函数给出非对称平行双线中TEM波的分布规律,通过数学软件Matlab绘制出TEM波在其横截面上的结构图,计算出其特性阻抗。研究结论对于计算该传输线的衰减常数、了解其功率容量、考虑功率耦合及设计有关的有源器件均有一定的参考价值,而且还可为一般的对称传输线的加工制作精度提供理论依据。
The solution of the TEM wave in asymmetric parallel bilinear can be obtained by first solving the electric field solution of the TEM wave by the solution of the electric field derived from the static field under the same boundary conditions by the fractional linear transformation on the complex coordinate system z Then the distribution of the magnetic field is obtained according to the relationship between the electric field and the magnetic field which is related to Maxwell’s equation. The distribution of the TEM wave in the asymmetrical parallel double line is given by the fractional linear transformation function. The TEM wave Its cross-sectional structure chart, calculate its characteristic impedance. The conclusion of the research has certain reference value for calculating the attenuation constant of the transmission line, understanding its power capacity, considering power coupling and designing related active devices, and can also provide theoretical basis for the processing accuracy of the general symmetrical transmission line.
