报告内容：Title: Electromagnetic Nanonetworks in the Terahertz Band

Overview:

Nanotechnology is providing a set of tools to the engineering community to design novel devices just a few hundred nanometers in size, which are able to perform only very simple tasks. Nanonetworks, i.e., networks of nano-devices, will enable more advanced applications of nanotechnology in the defense, military, biomedical and environmental fields. Scaling a metallic antenna down to a few hundred nanometers would impose the use of very high operating frequencies, thus, drastically limiting the communication range of nano-devices. Alternatively, graphene can be used to develop nano-antennas able to radiate at much lower frequencies. Interestingly, this frequency band matches the initial predictions for the operation frequency of graphene-based radio-frequency (RF) components in future nano-transceiver architectures. To date, however, it is not clear how nano-devices will communicate.

The fundamental research objectives of this seminar are to prove the feasibility of graphene-enabled electromagnetic communication among nano-devices and to establish the scientific foundations of electromagnetic nanonetworks in the Terahertz band. It contains: i) the state of the art of nanonetworks, ii) design of nano-machines includes graphene-based nano-antennas and high-speed nano-transceivers for Terahertz communications, iii) Terahertz channel model for short-range communication in nanonetworks, and iv) new information theoretic fundamentals of communication among nano-devices.
