| Abstract: | The multipole theory (MT) method was presented as a new approach for the analysis and design of various shielded multiconductor cables. The solution of boundary-value problem associated with the shielded multiconductor cable was represented by the generalized MT formula, and the procedure to obtain the capacitance of shielded multiconductor cable was described. Three representative computational examples, the deformed coaxial cable, the shielded balanced-pair transmission line and the cable consisting of 10 cylindrical conductors, were given to validate the theory, and to demonstrate the accuracy and flexibility of the MT method. |
