Abstract :
In this paper we demonstrate the accuracy of the FDTD technique in calculating the signal propagation characteristics of a twisted pair transmission line. The PML absorbing boundary condition is applied in non-orthogonal coordinates in order to accurately model the wire contours with minimal error from sidewall reflections. The effects of the wire dielectric coating as well as the wire twist are examined
