I am an experimental physicist in the electromagnetic and acoustic metamaterials group that has developed a speciality in characterisation of composite materials across the microwave region.
I am interested in the electromagnetic properties of composite materials and how they may be tailored to suit applications in microwave technologies such as antenna systems.
I graduated from Exeter University's CDT for metamaterial research, performing an investigation into the microwave characteristics of particulate magnetic composites. The aim of the project was to use 'onion skin' microparticles to better understand the way in which magnetic domains are formed and how they may be utilised to increase the frequency at which significant permeability may be achieved.
Since graduating I have taken on a role as post-doctoral research fellow at The University of Exeter. I previously worked on a NATEP project, developing a broadband AMC design for use with conformal antennas. This work was undertaken in collaboration with Technical Composite Systems and Cobham Aerospace Connectivity and was successful in producing an AMC prototype in-house that was designed subject to specific constraints provided by industrial partners. This project has lead to a second NATEP project, again working with Technical Composite Systems, this time to produce impedance matched composite materials for low-cost miniaturisation of antennas.
I have recently been performing an investigation into how microwave metasurfaces may be utilised in the food industry for improving the efficiency of cooking in conventional microwave ovens. This work is performed in partnership with QinetiQ, as part of TEAM-A, The Tailored Electromagnetic and Acoustic Materials Accelerator and is funded in part by an industrial partner, Pepsico.
I am now working part-time on a research project within SYMETA, Synthesising 3D Metamaterials for RF, Microwave and THz Applications. This work is undertaken in collaboration with EPSRC, University of Oxford, Loughborough University, Queen Mary University of London and The University of Sheffield. The project aims to investigate the ways in which additive manufacturing technology can be exploited to create novel, multi-functional 3D metamaterials.
