Abstract
This paper investigates how the PCB power-bus sturcture's characteristics are influenced by the loading of decoupling capacitors in conjunction to other lumped elements including vias. The fields and impedance profiles are rigously evaluated and analyzed on various cases loaded with the above components and their effects will be given to bring better PCB EMC countermeasurs.
