Wireless tracking and sensing technologies have become a vital part of our daily lives. To ensure accurate results, we need to transition towards terahertz (THz) frequencies, which are the future of wireless networks like 5G and beyond. In this frequency range, the wireless channel is highly sensitive to small changes. Our project aims to develop THz passive backscattering tags that will function with a monostatic THz reader, specifically, a leaky wave THz antenna. These tags must have a unique identity so that the reader can accurately identify and distinguish each tag and its position. Backscattering technology uses low-power and passive devices like envelope detectors, dividers, comparators, and impedance controllers, instead of more expensive and bulkier conventional components like local oscillators, mixers, and converters.

This project is linked with a project called "Terahertz Backscattering Device for High-Resolution and Single-shot Localization," funded by the Australian Government through the Office of National Intelligence. The project is open only to Australian or New Zealand permanent residents or citizens due to funding requirements. This is an excellent chance to contribute to the development of novel Australian Defence and intelligence technologies and work on an exciting project.

The student on this multidisciplinary project will work with TELE group academic staff, Dr Shaghik Atakaramians (expert in terahertz devices and components) and Dr Deepak Mishra (expert in backscatter communications). The student will also take part in the group meeting of the funded projects where they can benefit from mentoring of world-renowned exerts Prof Aruna Seneviratne and Prof Jinhong Yuan. The students will be part of EET cutting-edge research groups: Terahertz Innovation Group, Cyber-Physical System Group and Wireless Communication Group.

The interested student needs to be good in computer programming along with having basic knowledge of wireless communications and signal processing. We will be providing lectures on advanced concepts as a part of the training.

The project contains the design and simulation of THz tags with the following expected outcomes:

  1. The outcome for design: identifying a tag design that has a broadband signature.
  2. The outcome for simulation (CST Studio): Designing a terahertz tag operating at in D-band (103-170 GHz).
  3. Research outcomes: co-authorship in journal publication if successful in design and mentoring and support for PhD application.
  4. Other outcomes: A poster presentation and a brief video highlighting the main findings.
