Graphene can be used to absorb radio waves

Researchers from Queen Mary University and the Cambridge Graphene Centre demonstrated that graphene can be used to absorb electromagnetic radiation. This means that graphene coating can be used to stop radio waves from entering cars or buildings.

In their demonstration, the researchers supported a stack of graphene sheets on a metal place and placed it on a quartz substrate. This stacking configuration enabled them to control the interaction between the radio waves and the graphene.

The researchers now want to develop prototypes like wireless networks, with an aim to take the graphene-based technology from the lab to a real world application.
