Abstract
The present invention relates to a passive layer including graphene for the attenuation of near-field electromagnetic waves and heat dissipation. The passive layer blocks electromagnetic waves radiated from an external electronic device or prevents electromagnetic waves generated in an electronic device from emitting to the outside. The passive layer is designed to reduce interference between transmission circuits of a device in the near-field region or influence such as malfunction caused by external electromagnetic waves. The present invention also relates to an electromagnetic device and a circuit board, each including the passive layer.
