Abstract :
In this paper the analytic solutions of ground bounce problems on the power/ground plane structures of printed circuit boards (PCBs) are presented based on the perfect magnetic wall assumptions of the PCB´s edges. The Green´s function of the infinite power/ground plane is first derived, and then the sidewall reflections are replaced by the image sources, resulting the voltage expressions on the PCB explicitly. The numerical results are compared with the cavity-model analysis and measured data to validate the proposed approach.
