SWS03: Nanotechnology Applications of Antennas and Wireless Sensing

Wednesday - 1:30-4:20pm

Krishna Naishadham GeorgiaTech, USA

Patrizia Savi POLITO, Italy

Context

Carbon nanomaterials such as carbon nanotubes, graphene, nanoparticles, etc. continue to be investigated in antenna applications and electromagnetics, such as antenna tuning and reconfigurability, low-loss microwave absorbers, EMI shielding, and wireless sensors where the sensing element comprises some form of chemically functionalized nanomaterial. This short course introduces the basic high-frequency electrical properties of CNTs and graphene, and summarizes state-of-the-art in nanomaterials and their RF and THz applications, including antennas and guided wave devices. Antenna design and their integration with thin films of the nanomaterial used in passive sensor nodes, is discussed. Practical applications of nanotechnology in wireless chemical and biosensors are highlighted at a tutorial level. This workshop provides a tutorial introduction to nanomaterials and state-of-the-art applications of nanotechnology for practical deployment of antennas and related microwave circuitry on sensor platforms. 

Programme

The workshop will feature talks given by invited speakers with significant current research experience in nanomaterials, antenna design, microwave circuit design and wireless sensors. The speakers and their topics are listed below. Dr. Gomez-Diaz will focus on graphene, emphasizing novel antennas and plasmonic guided wave structures. Prof. Savi will discuss the RF characterization of nanocomposite thin films of graphene, CNT and biochar, an organic polymer with moderately high conductivity, and present planar antenna design concepts incorporating biochar. Dr. Naishadham will discuss several methods of antenna integration with carbon nanotube (CNT) and graphene thin-films in a multi-layered substrate, with attention to the sensor film isolation from the antenna element in order to minimize interference. Dr. Walter Fuscaldo will present a tunable leaky-wave antennas based on graphene in the THz Range
