Microwave characterisation of new magnetic and dielectric structures and materials. The main goal of the project is to characterize electromagnetic properties of single crystal dielectric and polycrystalline ferrite materials at microwave frequencies, from room temperature down to liquid helium temperature.

The main goal of the project is to characterize electromagnetic properties of single crystal dielectric and polycrystalline ferrite materials at microwave frequencies, from room temperature down to liquid helium temperature. Also cylindrical and spherical resonant Bragg structures will be investigated using some of these materials. The dielectric rod resonator technique will be used for all materials and the whispering gallery mode technique will be used to measure the lowest loss materials. Very accurately measured microwave parameters of electric and magnetic materials will be made available to designers of new components and systems (especially useful for operation at cryogenic temperatures).Read moreRead less
Investigations and characterization of new materials for wireless communications. The main goal of the project is to characterize electromagnetic properties of single crystal dielectric materials available from different sources at microwave frequencies, in a wide range of temperatures from room down to liquid helium temperatures. Two measurement techniques are proposed to be used for this purpose: the dielectric rod resonator technique for all materials and the whispering gallery mode technique ....Investigations and characterization of new materials for wireless communications.

A principal benefit to wireless communication is that very accurately measured microwave parameters of electronic materials will be made available to designers of new components and systems (especially useful for operation at cryogenic temperatures).Read moreRead less
Verification and prototypes of Opto-ULSI Processors for MicroPhotonic Applications. The aim of the program is to establish efficient linkage between Australia and Korea by stimulating research towards the rapid integration of VLSI systems into photonic components, hence creating a new platform in intelligent MicroPhotonic systems, which are core elements for future-generation reconfigurable telecommunication networks. Our ultimate target is to (1) design a low-power 256-phase Opto-ULSI processor ....Verification and prototypes of Opto-ULSI Processors for MicroPhotonic Applications. The aim of the program is to establish efficient linkage between Australia and Korea by stimulating research towards the rapid integration of VLSI systems into photonic components, hence creating a new platform in intelligent MicroPhotonic systems, which are core elements for future-generation reconfigurable telecommunication networks. Our ultimate target is to (1) design a low-power 256-phase Opto-ULSI processor, (2) experimentally verify various reconfigurable MicroPhotonic architectures for optical telecommunication applications, (3) develop efficient software for the various MicroPhotonic systems, and (4) develop and verify working prototypes.Read moreRead less
A comprehensive approach to development and understanding of III-nitride-based high performance electronic devices. This project forms part of a long-term, international research program into the development of high-power, high-frequency electronics for high performance radar and communications systems. The advanced fabrication technologies and designs being investigated in this project fall well within the designated priority goal of Frontier Technologies. III-nitride (GaN, AlN, InN and alloys) ....A comprehensive approach to development and understanding of III-nitride-based high performance electronic devices. This project forms part of a long-term, international research program into the development of high-power, high-frequency electronics for high performance radar and communications systems. The advanced fabrication technologies and designs being investigated in this project fall well within the designated priority goal of Frontier Technologies. III-nitride (GaN, AlN, InN and alloys) technology is also of high interest to defence organisations, as radar and satellite-communications links, which operate at frequencies ranging from hundreds of MHz to tens of GHz, often have high power-amplification requirements. The project therefore also falls within the priority goal of Transformational Defence Technologies.Read moreRead less
