Analysis of the Effect of Graphene Sheet Coating on Shielding Effectiveness for Shielding Enclosures with Different Aperture Shapes

Electromagnetic compatibility (EMC) has become much more important especially over the last decade due to incorporating advanced driver assistance and electric propulsion systems into conventional vehicle architecture. shielding is a conductive barrier used for protecting electronic circuits against external electromagnetic interference (EMI). Shielding effectiveness (SE) measure of performance an interfering source. Design limitations inside vehicles (EV) forces investigate on increasing SE without changing enclosure dimensions. Graphene widely in many studies its good conductivity strong structure. In this study, numerical model which inner surfaces are coated with graphene sheets, designed. The effect different aperture shapes analyzed according coating sheets.
