Microwave Antennas and Waveguides in Photonic Crystals. We propose to design a revolutionary new class of microwave antennas and antenna arrays in photonic crystals, which can shield, localise and guide electromagnetic radiation in a dielectric environment. This design is completely devoid of metal, thereby eliminating skin-effect losses that are the dominant limitation for planar antenna arrays at upper microwave (millimetre-wave) frequencies. Our new design will achieve high radiation efficie ....Microwave Antennas and Waveguides in Photonic Crystals. We propose to design a revolutionary new class of microwave antennas and antenna arrays in photonic crystals, which can shield, localise and guide electromagnetic radiation in a dielectric environment. This design is completely devoid of metal, thereby eliminating skin-effect losses that are the dominant limitation for planar antenna arrays at upper microwave (millimetre-wave) frequencies. Our new design will achieve high radiation efficiencies and antenna gains not possible with existing planar technology, thereby enabling new applications of planar antenna arrays, for example to radio astronomy, as well as greatly improving existing applications.Read moreRead less
New regularisation techniques in electromagnetic diffraction from cavities and related complex scatterers. Modern technology, such as radar and other imaging devices, exploits the information carried by electromagnetic waves. New technology depends centrally upon advances in the mathematics of waves to give precise, reliable and effective means of predicting how objects capture and re-radiate wave energy in the scattering environment. This project aims to develop a new mathematical approach to w ....New regularisation techniques in electromagnetic diffraction from cavities and related complex scatterers. Modern technology, such as radar and other imaging devices, exploits the information carried by electromagnetic waves. New technology depends centrally upon advances in the mathematics of waves to give precise, reliable and effective means of predicting how objects capture and re-radiate wave energy in the scattering environment. This project aims to develop a new mathematical approach to wave scattering by objects with complex scattering mechanisms, as typified by cavity structures. This new formulation is obtained by a process of analytical regularisation of the equations describing the scattering process. It generates algorithms more reliable and computationally accurate than current codes.

Electrodynamics of the High Latitude Ionosphere. Electrical power (~10^12 W on average), incident over the high latitude ionospheres drives auroral displays, causes magnetic disturbances and other space weather effects over the globe, including Australia. This project uses Iridium, a US$6 billion, commercial satellite constellation, to study energy deposition into the ionosphere from near-Earth space. The Iridium data is not public domain. This project provides data access, representing a signif ....Electrodynamics of the High Latitude Ionosphere. Electrical power (~10^12 W on average), incident over the high latitude ionospheres drives auroral displays, causes magnetic disturbances and other space weather effects over the globe, including Australia. This project uses Iridium, a US$6 billion, commercial satellite constellation, to study energy deposition into the ionosphere from near-Earth space. The Iridium data is not public domain. This project provides data access, representing a significant cost-effective way for Australia to participate in observational space science. Australian postgraduate training is an integral part of the project, providing international level access and interpretation of scientific satellite and over the horizon radar network data.Read moreRead less
