ABSTRACT:
An electromagnetic-wave suppression structure in a multilayer PCB or package structure is supplied with a power to be used therein by a power distribution network including a power plane and a ground plane. The multilayer PCB and package includes: an electromagnetic-wave suppression structure including an electromagnetic band-gap; and the electromagnetic-wave suppression structure is formed at a specific portion(s) of the power plane and/or the ground plane to suppress noises.
