The information society in which we live requires increasingly high bandwidth, low cost communications. This project addresses two critically important technologies needed to meet these demands: signal processing devices and antennas. These devices will be designed using three-dimensional photonic crystals, which provide excellent possibilities for low-cost, highly integrated photonic circuits. Working prototypes will be built at microwave frequencies, but due to the scalability of electromagnetic theory these results are also valid in the optical domain. The outcomes of this project will be accurate theoretical models and empirical tests for new technologies that satisfy the future needs of the information society.Read moreRead less

The proposed facility is for testing broad-beam microwave antennas (1 GHz - 18 GHz), designed and developed by collaborators for several research and commercial projects. These antennas are important in telecommunications, defence and biomedical applications. While facilitating timely pattern measurements of antenna prototypes, it will open new opportunities in antenna experimentation. This facility will enhance collaborators' highly acclaimed theoretical research by providing experimental results for theory validation. Near-field patterns available from the facility will advance our knowledge on complicated antennas. This will generate researchers skilled in state-of-the art antenna measurements, and will help develop competitive Australian industries in this frontier technology.Read moreRead less

The aims of the project is to gain better understanding of spatial characteristics of wireless communication channels; and to apply spatial signal processing theory to design receivers for wireless systems. The expected outcomes of the projects are new system theory for spatial signal processing, a new spatial model to characterize wireless communication channels, categorize a relationship between scattering environment antenna spacing and multi-element antenna system capacity, and novel use of multiple antennas to improve the performance of wireless systems. Success in this investigation could have wide applications in the development of future mobile and fixed wireless communication systems.Read moreRead less

The Giant Cuttlefish population in Spencer Gulf is the largest in the world and is highly valued by local residents, the tourism industry and the recreational diving sector.

But surveys over the last 13 years has indicated that the northern population has, and continues to, decline markedly - leading to major public consternation.
The Spencer Gulf Prawn Fishery is known as one of the best managed trawl fisheries in the world and is permitted to only land three species, the western king prawn, bugs and southern calamari
A recent SARDI study correlated the observed decline in Cuttlefish abundances with a range of potential factors including: water temperature, weather, pollution (including those from increased shipping activities), predators, prey, habitats, diseases, fishing pressure and tourism. Of these, rainfall was the only factor found to correlate inversely with peak cuttlefish abundance. The study noted the incidental capture of Giant Cuttlefish in the Prawn Fishery but found no clear association between the decline in cuttlefish and fishing intensity. The study noted a positive correlation between trawl effort and the size of the cuttlefish population but this relationship is counter-intuitive and is likely to be coincidental. The evidence therefore does not support an assertion that the recent decline in the abundance of Giant Cuttlefish in northern Spencer Gulf has been caused by prawn trawling or any other forms of fishing.
Nevertheless, due to the low population numbers, all sources of potential mortality of cuttlefish, including that from prawn trawl bycatch, need to be minimized urgently and carefully managed. This project is focused on an attempt to reduce the bycatch of cuttlefish in this fishery using modifications to the trawls used (termed ‘bycatch reduction devices’ or ‘BRDs’). If successful, such BRDs should be suitable for use in locations and at times where cuttlefish bycatches are significant.
Objectives: 1. To test four grid-based designs to determine the best way forward in developing a BRD for this fishery that excludes cuttlefish and crabs, yet does not reduce prawn catch by any more than approx 6% and has a negligible variation in the grade composition of prawns. Read moreRead less
