Abstract: 

Wireless sensing using electromagnetic (EM) signals provides a way to non-destructively or remotely discover properties of the volume of interest. Such systems work by using one or more EM sources and multiple receiving locations to observe how the EM signals interact with their environment. Information gained can provide information about the spatial distribution, the permittivity and conductivity, based on how the signals reflect and transmit through the environment.

This presentation will present two different applications of wireless sensing. The first of these is EM medical imaging, which involves producing an image showing the contrast between abnormalities in the body such as bleeds, obstructions and tumours compared to healthy surrounding tissues. With appropriate algorithms, this technique inherently has the potential to be low-cost, portable and fast compared to existing imaging modalities. 

The second application is the application of radar for transport monitoring and defence applications. This system involves the detection of moving objects such as vehicles and aircraft in the environment. Algorithms provide detection capability via multiple antennas providing both the target location as well as its velocity vector. Also, for traffic monitoring, RFID is used to identify a vehicle, and signal processing is used to detect anomalies including vehicle fitness and abnormal driving behaviour.

Biography: 

Konstanty Bialkowski received his dual B.Eng./BSc degree with first class Honors, and PhD in Wireless Communications from the University of Queensland, Australia in 2003 and 2008 respectively. He worked as a Research Engineer at National ICT Australia (NICTA), prior to joining the School of ITEE at the University of Queensland in 2009, where he worked as a research fellow where he is currently an Advanced Queensland Fellow Fellow. His research interests include biomedical imaging systems, passive radar systems and wireless communications. He was awarded the early career researcher award at the 2011 Australian Communication Theory Workshop. He is an Associate editor for the IEEE Journal of Electromagnetics, RF and Microwaves in Medicine and Biology (JERM).
