Prediction of noise in multiconductor transmission lines excited by multiple radiation sources

This study derives an analytic expression for voltages and currents in multiconductor transmission lines (MTL) excited by multiple radiation sources (MRS) at arbitrary locations. Modified telegrapher's equations are used to solve for the line voltage and line current in MTL with distributed voltage and current sources caused by the electric and magnetic coupling of external fields. The fields from MRS are considered as the incident fields on MTL. To verify our approach, we computed the terminal currents for both two transmission lines and four transmission lines excited by an electric dipole and compared the results with those of a commercial electromagnetic solver.
