Terahertz (THz) microresonators enable extreme field confinement and high Q resonances, key ingredients for next-generation communication (6G), spectroscopy, and on-chip THz photonics. Their performance hinges on exceptionally high-quality factors (Q) and pristine mode structures. Any defects will deteriorate their performance.
This project investigates the use of electromagnetic simulations to detect and characterise defects in terahertz (THz) microresonators. A reference resonator will be modelled and compared with structures containing controlled geometric or material defects. Changes in resonant frequency, Q-factor, spectral response, and electromagnetic field distribution will be analysed to assess the resonator's sensitivity to different defects.
The project will develop a simulation framework that can support non-destructive defect detection and quality control of THz devices, with potential extension to automated or machine-learning-based defect identification.

The project will be conducted in the Terahertz Innovation Lab at UNSW, providing access to a collaborative research environment with regular weekly group meetings and support from peers for discussion, problem-solving, and knowledge exchange.
- The project is expected to provide insight into how different types of defects affect the resonant behaviour of THz microresonators, including how the response varies with defect type, size, and location.
