Precision clocks are a key enabler for many important technologies including navigation, radar, distributed computing and communications. Unfortunately, the very best clocks are currently bulky and very expensive. This project will take Australia’s multi-award winning sapphire clock technology and transform it so that its unmatched performance is available from a unit with an order of magnitude smaller size, power consumption and cost. This transformation will be driven on the back of a patented revolutionary step that allows operation of the sapphire clock at higher cryogenic temperatures. The new clock will have a wider range of applications delivering more computational power, higher bandwidth transmissions and better radar. Read moreRead less

Silicon will be a key material for both types of terahertz structures to achieve highest efficiency. Effective medium theory will enable performance, functionality, and integrability, while maintaining structural simplicity for cost benefits. The expected outcomes will replace decades-old costly hyper-hemispherical lenses for future terahertz systems in fixed wireless backbone beyond 5G and short-range see-through radar and imaging.Read moreRead less

This project aims to establish terahertz measurement capabilities to further Australia's strength and momentum in terahertz research. This will comprise of two terahertz extension modules, working with a dedicated vector-network analyser, and high-precision probes and probe station. The project will enable point-feeding, monochromatic, coherent, and fine spectral-resolution measurement at an atmospheric window of 220-330 GHz. The capabilities are essential for development of two-dimensional materials, active components, waveguides, and antennas towards a common goal of efficient integrated terahertz devices and systems. The project will serve emerging terahertz applications including standoff imaging and short-range high-speed data transmission. This will have broad impact in the areas of surveillance, biomedicine, security, and public safety and well-being.Read moreRead less

This project aims to improve the Cospas-Sarsat search and rescue system to ensure faster, more reliable, more accurate, and more cost-effective search and rescue operations, ultimately saving lives. The satellite-based Cospas-Sarsat system has assisted with the emergency rescue of more than 35 000 lives worldwide since its introduction in 1982. A second generation of this system is currently under development, promising to significantly improve detection rate and localisation accuracy. However, in an emergency, the system’s performance is often compromised due to interference and atmospheric effects, leading to false detections that waste valuable resources. This project aims to develop novel techniques to improve this performance.Read moreRead less

The outcomes from the project are expected to underpin innovative applications, such as aged care, providing a means for caregivers to automatically monitor health and physical activity and intervene as required. Such applications would support ageing Australians to live with greater independence and safety.Read moreRead less
Unconventional antennas from macro- to nano-scales. This research project will develop unconventional radio-frequency antennas for tomorrow's miniaturised multi-function wireless communication systems. It will also extend the principles to resonant nano-structures or 'optical antennas' which offer new perspectives in sensing physics, with the possibility of single molecule detection and identification.
Reconfigurable polymer antennas. This research will utilise conductive polymers, or 'synthetic metals', as flexible and smart materials for radio-frequency antennas technology. The created antenna prototypes will find applications in biomedical devices (for example, for wearable devices and implants), for tagging (identification), and in reconfigurable antennas for wireless communication.
