Innovative CUDOS researchers secure funding for industry Linkage Projects


The innovative research of CUDOS scientists at Macquarie University and the Australian National University (ANU) has led to significant funding in the latest Australian Research Council (ARC) grants for Linkage Projects.

Putting photonics in sewers


CUDOS Chief Investigator Professor Michael Withford and Dr Martin Ams, in collaboration with Macquarie University researchers and Sydney Water Corporate, received ARC Linkage Projects scheme funding to develop a photonic sensor capability to measure chemical compounds that cause concrete corrosion in waste-water pipes.

Sustainable management of urban waste-water networks is a global problem, with hydrogen sulphide and water in air pockets causing concrete attack that results in premature pipe failure with high financial, public health and environmental costs. Unlike current qualitative methods, which rely on often dangerous visual inspection of pipes to identify concrete corrosion, Withford’s and Ams’ project will develop a quantitative sensing system that directly measures key chemicals, targeting the cause and not the effect. This research is expected to extend the life of waste-water networks and reduce cost to the public.

Beam steering by Huygens metasurfaces for sensing applications

self-navigating car

With funding from the ARC’s Linkage Project scheme, the research team at ANU, including CUDOS scientists Dr David Powell, Professor Dragomir Neshev, Dr Ilya Shadrivov and Professor Yuri Kivshar, aims to develop steerable radar systems for navigation sensors and surround monitoring in vehicles, using antennas operating in the millimeter-wave range.

The boom in radar sensing technologies used for safety and comfort in cars has stimulated the need for cost-effective directional antennas for beam-steering in sensing applications. This project will use the recently discovered concept of Huygens metasurfaces, which enable cost-effective devices with low transmission losses and strong tuning of beam-steering angle. The research team will collaborate with IEE S.A. and the Asian Office of Aerospace Research and Development, and expects that the wider availability of such radars will enhance collision prevention systems, adaptive cruise control and ultimately help create self-navigating cars.
