| Abstract: | A new method for calculating 2D electrostatic field boundany-value problem-Multipole Theory (MT) method is described. A set of characteristic impedance formulae for rectangular cross-section, magnetic and electric wall type slab- line with cylindric inner conductors is presented by the MT method. By calculating the characteristic impedances of various shielded rectangular cross-section slab-lines with cylindric inner conductors,it is shown that the MT is a more effective approach for the analysis of the shielded rectangular cross-section slab-lines with cylindric inner conductors,it is reliable and may be used to calculate the slab-line engineering problems. |
