Abstract

An improved boundary element method (BEM) for the calculation of the capacitance matrix in a multiconductor transmission line structure is presented, where the edge singularities of the charge and current near the corners of the cross-sections of the signal lines are embedded in the basis functions. The new method demonstrates improved accuracy and enhanced computational efficiency in comparison to previous methods. The results for the new algorithm are compared with those for other approaches presented in the literature
