PhD: 3D Design and Modelling of Ultra Flexible Antennas using Unstructured Transmission Line Method (UTLM) for Wearable Communications Applications
Supervisors: Dr Ana Vukovic, Prof Trevor Benson and Prof Phillip Sewell
Flexible antenna design for wearable communications is challenging due to its close proximity to human body as well as easily effected by body movement that alter the properties of the antenna. Computational simulation of flexible antenna has also proven difficult especially in modelling the extreme curvature introduced on antennas. Hence, my research explores 3D design and modelling using in-house Unstructured TLM software in order to precisely model extreme curved boundaries of flexible antennas while performing analysis on its transmission characteristics in the interest of the bending and crumpling effect.
PhD: Cyber-Physical System for Evaluation PWM Techniques Influence on EMI of Converters
Supervisors: Dave Thomas, and Mark Sumner
Recent advances in smart industrial systems enabled by Cyber-Physical System (CPS) technologies, have led to more resilient systems in respect of coding and operation and, ultimately, to an innovative system with adaptable features. Nevertheless, among the various factors influencing smart industrial systems, electromagnetic compatibility (EMC) stands out. The philosophy of the standardization of electromagnetic interference (EMI) emission levels aims to regulate and certify that an environment ensures the EMC between all the installed systems and infrastructures. Thus, due to their convergence of computation, networking, and control of physical processes, the CPS has been frequently used as a control system for bench level testing for one of the big EMI sources in the industrial environment, i.e., power electronic converters. Among many methods of improving the EMC of converters, we may use improved control techniques. In addition to the primary function of controlling energy conversion, such a control technique can reduce the level of conducted EMI by spreading the harmonics on a broader frequency range. A Field-Programmable Gate Array (FPGA) may be used for the cyber-physical implementation of such controls and provided the possibility to design new “EMC friendly” control techniques for power electronic converters.
PhD Title: Design the next generation of electromagnetic systems for 3D printing applications
Supervisors: Dr Juliano Katrib, Dr Georgios Dimitrakis, Prof Samuel Kingman, Dr Chris Dodds
We seek to develop a novel microwave process to manufacture and produce high quality 3D printed products. This will involve the design and implementation of novel microwave systems and to understand the property of the material and its application in industry. There is a growing need for innovative work in this topic area to address key challenges in manufacturing engineering and sustainable process. The work will begin with an extensive electromagnetic simulation, characterization and modelling phase. Once successful solutions had been identified, laboratory-based testing will begin to allow practical validation of the ideas followed by implementation and validation of the process in our dedicated laboratory and in Australia in collaboration with CSIRO.
PhD Title: Optimal simulation of converter emissions for first time right design.
Supervisors: Prof David Thomas, Prof Stephen Greedy
To develop methodologies for efficiently modeling the conducted emissions from power electronic converters including the common mode, including model development, measurement, and data processing, such to achieve coexistence between power electronic, and sensor and communication systems. To include all the source and coupling paths in the converter, as well as the measurement system so as to provide a direct comparison with measured results.
