FEM vs. Modal Method in the MTL Analysis

The aim of this paper is to present a new numerical model for multi-conductor transmission line (MTL) analysis in frequency– domain. The proposed model based on the finite element method (FEM) is compared with traditional technique such as the modal method. Applying analytical solution of the telegrapher's equations we can construct the finite element local system of equations and apply standard assembly procedure. Capability of modern computational software tools with built-in numeric functions allows us to simplify necessary calculations in numerical procedure.
