Co-planar microwave integrated circuit transmission lines based on carbon nanotube and graphene / Mohsen H S Ben Kara

The aim of this work is to study the feasibility of using carbon nanotube and graphene as new conductor materials for microwave integrated circuits (MMIC). As the dimensions of integrated circuits scale down to nanometers, the conductor resistance at high frequencies increase due to skin effect, and...
