| Abstract: | The linear boundary element method(LBEM) is presented as a approach for the analysis and design of various symmetry shielded multiconductor cables.Two representative computational examples,the deformed shielded balanced pair transmission line and the deformed shielded cable consisting of 3 cylindrical conductors,are given to validate the theory.To demonstrate the accuracy and flexibility of the LBEM,the influence of the deformation degree of the last two cables on the results are discussed,and the curves of the coupling capacitance that the influence of the deformation degree of the latter two cables at different location and the suitable location for laying of cables are given. |
