Graphene: A Wireless Wonder

Graphene, an allotrope of carbon, have recently attracted the wireless researchers working in the communication field, owing to its typical electromagnetic and optical characteristics.  Graphene can be seen as a mono-atomic thick layer of graphite and have a two dimensional hexagonal structure. It exhibits a saturable absorption property at microwave and tetrahertz band. And, it is this property which makes Graphene a wonder wireless in the eyes of wireless research fellows.
