Current activities
Dr David Miljak is a Research Scientist at CSIRO Process Science and Engineering. He leads the research in radiofrequency (RF) and optics based at the Lucas Heights site in NSW.
His current research interest is the development of magnetic resonance and other RF methods for determination of composition, mineralogy and other physical parameters.
Dr Miljak projects include the investigation of RF sensors for online determination of copper and iron ore mineralogy, as well as other non-minerals applications.
Dr Miljak's expertise includes:
- radio field interaction with materials
- design of efficient RF sensors, through experiments and modelling
- low and high power RF engineering
- advanced radio receiver design.
Background
Dr Miljak completed his doctorate in 1995 on the propagation of radio waves in hot ionised gases (plasmas).
He then went on to hold several postdoctoral positions at the University of California, Los Angeles (UCLA) and the Australian National University, Canberra, studying radio wave propagation in both low and high temperature plasmas.
Dr Miljak joined CSIRO in 1999 as a Project Scientist to work on RF analysis of minerals.
Since then he has led numerous projects in on-conveyor microwave moisture analysis for industrial applications. He has also been active in the development of magnetic resonance sensors.
His microwave work led to the commercialisation of a low frequency microwave (LFM) moisture analyser.
Academic qualifications
Dr Miljak has been awarded a:
- Bachelor of Science (First Class Honours) in Physics from the University of Sydney, New South Wales, Australia
- Doctor of Philosophy in Plasma Physics from the University of Sydney.
Dr Miljak’s thesis was titled Alfvén waves in a tokamak plasma.
Achievements
Dr Miljak was awarded a CSIRO Minerals Innovation Award for development of a low frequency microwave moisture analyser.
He is also the author of several patents and applications and over 20 research papers in radio-based applications.
