Abstract

This paper presents a boundary element analysis of transmission-line parameters on the basis of the quasi-TEM assumption. Singular boundary elements are employed to adequately express the corner singularities at sharp conductor edges. The boundary integrals consisting of the Green´s function and singular interpolation functions are regularized by a Taylor expansion technique, and are then evaluated using the standard Gaussian quadrature. The numerical results for test problems show the reliability of the present method
