Abstract: Previously developed numerical methods for predicting radiated emissions from parallel wire structures are extended to alternative geometries. Methods based on obtaining approximate current distributions using classical transmission line theory are compared to Moment Method results. Twisting and ground planes are investigated for their effects on electromagnetic radiation characteristics. Numerical simulation results are compared and used to illustrate alternatives in system configuration and their impact on total system functionality and compatibility.

Keywords: automotive electronics; electrical noise; line geometry; radiated emissions; signal lines.
