EPSRC CDT in Metamaterials: Design and characterisation of 3D metamaterials fabricated using additive manufacturing

University of Exeter - Departments of Physics and Astronomy, and Department of Engineering

The studentship is part of the EPSRC Centre of Doctoral Training in Metamaterials (XM2), www.exeter.ac.uk/metamaterials. Our aim is to undertake world-leading research, while training scientists and engineers with the relevant research skills and knowledge, and professional attributes for industry and academia.

Supervisors: Prof  J R SamblesProf A P HibbinsDr R C Mitchell-Thomas

This PhD project is part of a 5-year EPSRC Grand Engineering Challenge project, “SYnthesizing 3D METAmaterials for RF, Microwave and THz Applications”, which began in March 2016.  SYMETA's grand vision is to deliver a palette of novel, multi-functional 3D metamaterials using emerging additive manufacturing (AM), with the potential to support a single 'design-build' process. Exeter’s role in this project is to bring expertise/facilities for designing, modelling and characterising novel meta-atoms for operation across the RF and mm wave regime. An example of our previous work in this area can be found in Parke et al., Applied Physics Letters 106, 101908 (2015).

The development of meta-atoms through modelling and experimental characterisation is the primary objective of this studentship. It will establish the underpinning principles that govern meta-atom metamaterial components. We will first design a series of meta-atoms, and model their EM response in arrays. Then, we will fabricate and experimentally characterise the EM behaviour of small test-samples. These materials will be designed to possess extraordinary electromagnetic properties, for example near-zero index regions, impedance matched regions, extreme anisotropy and spatially graded parameters. Successful meta-atom designs will be passed to other consortium members for manufacture using AM techniques.

The PGR working on this studentship will be required to travel to partner institutions to discuss and monitor fabrication processes and progress.  He/she will also work closely with the Research Fellow (5 year) funded by this project.

4-year studentship: for UK/EU students, the studentship includes tuition fees and an annual stipend equivalent to current Research Council rates; for international students (non-EU) a very small number of fees only studentships may be available
