Title : Electromagnetic bandgap and metamaterial-inspired common-mode filtering structures

Abstract – Common mode noise in high-speed differential signaling results in significant signal integrity and unintentional EMI concerns. Past work has shown that common mode filters using electromagnetic bandgap (EBG) and complementary split-ring resonator structures can be implemented using standard PCB technology and are effective in suppressing common mode transmission in differential interconnects. When implemented in a multilayer PCB environment, this common-mode energy, when filtered, can result in crosstalk through coupling to parallel-plane waveguide modes. Recent collaborations between Rose-Hulman, IBM Research Triangle Park and the EMC Laboratory at L’Aquila, Italy have explored the use of via stitching and fences as one means of mitigating and improving performance of these common-mode filtering structures.
