Review of Microwave Devices using Carbon Nanotubes

Unique properties of Carbon Nanotubes (CNTs) and its mixture with polymers make them very interesting material for sensor application. Various chemical and electrical CNT-based sensors have been developed using technology such as infrared, laser, microwave, electrical capacitance, ultrasound and extra. In the past two decades researchers attempted to use carbon nanotube in microwave method for sensing application. In this paper passive and active RF and microwave circuits are envisaged to be implemented using carbon nanotubes in recent years due to their small size and electromechanical properties. Th ese devices are including switches, filters, antenna, resonators, oscillators, Nano Electro Mechanical Systems (NEMS) and mixers.
