Highly-Effective Integrated EMI Shields with Graphene and Nanomagnetic Multilayered Composites

Abstract

Electromagnetic interference (EMI) control is one of the most significant challenges for emerging consumer, automotive, Internet of things (IoT) and wearable systems. This paper demonstrates miniaturized and integrated nanostructures for component-level EMI isolation and external EMI shielding in ultra-miniaturized electronic systems. Multi-layered nanomagnetic and copper shielding materials are designed, synthesized, and characterized for their shielding effectiveness. Graphene is explored as an alternative EMI shield material. From the modeling and experimental analysis, the advantages of nanostructures for internal and external component-level shielding in different applications is discussed.
