The studentship is part of the UK’s Centre of Doctoral Training in Metamaterials (XM2) based in the Departments of Physics and Engineering on the Streatham Campus in Exeter. 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.
The 4 year studentship is funded 50:50 by an industrial sponsor and the College of Engineering, Mathematics and Physical Sciences at the University of Exeter. It is of value around £105,000, which includes £13,000 towards the research project (travel, consumables, equipment etc.), tuition fees, and an annual, tax-free stipend of approximately £16,500 per year for UK/EU students.
Eligible candidates: UK/EU nationals only due to industry sponsor requirements.
Exeter has a well-established and strong track record of relevant research, and prospective students can consider projects from a wide variety of fields:
- Acoustic and Fluid-dynamical Metamaterials
- Biological and Bio-inspired Metamaterials
- Graphene and other 2D Materials, and related Devices

The studentship is subject to funding availability.
Statement of Research
Joint supervisors: Prof. C. David Wright and Dr Jacopo Bertolotti
External partner: AWE PLC (Dr A. J. Comley)
Inertial confinement fusion (ICF), a scheme in which powerful lasers are used to compress and ignite a cryogenic pellet of deuterium-tritium fuel, is one route towards a clean energy source of the future . Conventional approaches to laser fusion demand extremely large and high-energy laser systems to initiate fusion, and this is proving to be a key limitation for the viability of ICF as a future energy source. In this project we aim to overcome such limitations by using novel metamaterials and metasurfaces to achieve multi-state beam zooming and deflection in ICF systems, massively increasing the coupling efficiency of the laser energy to the fuel pellet .
We will also explore the use of dynamic laser beam control with metasurfaces for other technologically important applications, such as laser-machining and LIDAR, working from the IR through to the UV wavelength range.
Working with AWE scientists to define zooming specifications, a range of meta-device options will be explored. Building on previous work [3, 4], the operating principle of the meta-devices could be based on (but not limited to):
1. Mie resonances in all-dielectric structures, including dual-resonant structures incorporating nonlinear element(s);
2. Structures incorporating phase-change materials;
3. Charge carrier injection techniques.
The performance of the proposed structures will be analysed using detailed electromagnetic and thermal simulations and promising prototype systems will be fabricated and experimentally characterised in the laboratory.

Metamaterials are fabricated microstructures having properties beyond those found in nature. They are an important new class of electromagnetic and acoustic materials with applications in many technology areas: energy storage and improved efficiency, imaging, communications, sensing and the much-hyped ‘cloaking’. Having recruited nearly 70 new PhD researchers in its first four years, the EPSRC Centre for Doctoral Training (XM2) hosted by the University of Exeter (www.exeter.ac.uk/metamaterials) will admit its fifth cohort of PhD students in September 2018.
The first year of the studentship includes an assessed, stand alone project, and a substantial programme of training. Students will choose from a wide range of taught modules, and participate in academic and personal development skills-based workshops, together with creativity events and conference-style meetings. The cohort will also be expected to disseminate their results to the international community via high-impact publications and international conferences. They will spend time working with our academic and industrial partners. Full details of the programme are available here, or download a copy of our prospectus.
The University of Exeter combines world class research with excellent student satisfaction. It is a member of the Russell Group of leading research-intensive universities. Formed in 1955, the University has over 20,000 students from more than 130 different countries. Its success is built on a strong partnership with its students and a clear focus on high performance. Recent breakthroughs to come out of Exeter's research include the identification and treatment of new forms of diabetes and the creation of the world's most transparent, lightweight and flexible conductor of electricity. Exeter is ranked amongst the UK’s top 10 universities in the Higher Education league tables produced by the Times and the Sunday Times. It is also ranked amongst the world’s top 200 universities in the QS and Times Higher Education rankings.
Eligible applicants: UK/EU nationals only.
During the application process you will need to upload the documents listed below. Please prepare these before starting the application process.
- Degree transcript(s) giving information about the qualification awarded, the modules taken during the study period, and the marks for each module taken.
- An academic CV;
- A cover letter outlining your research interests in general, the title of the project you are applying for;
- A Personal Statement consisting of two parts*:
- Describe a) why you would like to study for a PhD, b) why you would like to focus on this particular topic, c) any relevant expertise and d) your future career ambitions;
- Describe the qualities that you believe will make you a great researcher (in particular as part of a team).
You will be asked to provide the contact details of two academic referees.
* We foster creativity and utilisation of individual strengths. Applicants are encouraged to provide evidence to support their statements. This might include conventional written documents (e.g. examples of work), but we also encourage alternatives such as audio or video recordings, websites, programming etc. Please ensure to include accessible links to such files in an appropriately named document as part of the upload process.
Applications will normally be reviewed within two weeks of receipt from February 2019.
Candidates will be short-listed against a set of agreed criteria to ensure quality while maintaining diversity. Failure to include all the elements listed above may result in rejection.
The essential criteria:
- Undergraduate degree in a relevant discipline (minimum 2:1);
- Vision and motivation (for research & professional development);
- Evidence of the ability to work collaboratively and to engage in a diverse community;
- Evidence of excellent written and oral skills in English.
The highest quality candidates will also be able to demonstrate one of more of the following:
- Specialist knowledge about one or more of the 8 research areas listed above;
- Training in research methodology (e.g. undergraduate research projects);
- Research outputs (e.g. papers) and/or other indicators of academic excellence (e.g. awards).
Shortlisted candidates will be invited to an entry interview to assess fit to the CDT concept. This will be held prior the academic interview with the supervisors and will normally be undertaken by a panel of 3 people, including a current postgraduate researcher or post-doc in Physics or Engineering.
Interviews are expected to start in February 2019. It is therefore advisable to apply as soon as possible.
Please email email@example.com if you have any queries about this process.
