Summary:
An effective method is proposed to enhance the SI and PI of a power-bus structure(PBS) in a layered medium PCB by suppressing the EMI-causing resonance mode. It is implemented by a complementary split-ring-resonator as a 1-cell metamaterial-inspired geometry formed in the PBS to remove the resonance that hinders the signal transfer from one layer to another. The method is verified by the full-wave simulation and impedance measurement and RE test.
