| Abstract: | Based on the electrostatic field theory and transmission line theory, characteristic impedance and cut off wavelength of special section coaxial transmission lines are calculated using Finite Element Method (FEM). Through calculating and analyzing some engineering problems, it is proved that the method is of high accuracy, common usefulness and can be applied generally for the analysis of TEM transmission lines. |
