Fast parameter extraction for transmission lines with arbitrarily-shaped conductors and dielectrics using the contour integral method

Abstract

This paper presents an accurate surface formulation based on the contour integral method and the Dirichlet-to-Neumann operator to calculate the impedance and admittance parameters of transmission lines of arbitrary shape. The formulation only requires a discretization of the boundaries of the conductors and dielectrics, as opposed to the entire cross-section, which results in fast computations.
