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.
