INTRODUCTION The routing of the traces on a Printed Circuit Board (PCB) largely effect the ElectroMagnetic Compatibility (EMC) performance of the PCB with respect to both ElectroMagnetic (EM) radiation as susceptibility to EM-fields. The PCB will connect electronic components such as passive components, transistors and ICs. Furthermore, cables to interconnect the PCB with other system parts, e.g., another PCB, signal generator, CATV wall-outlet, DC power source or an AC-mains connection, will largely influence the PCB wi……
