EPSRC CDT in Metamaterials/Prosperity Partnership TEAM-A (PhD Studentship): New materials and structures that control the propagation of acoustic radiation

University of Exeter - College of Engineering, Mathematics and Physical Sciences

The studentship is part of the UK’s Centre of Doctoral Training in Metamaterials (XM2) and the Prosperity Partnership programme Tailored Electromagnetic & Acoustic Materials Accelerator (TEAM-A), based in the Departments of Physics and Engineering on the Streatham Campus in Exeter.  Its 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 studentships is of value around £90,000, which includes £11,000 towards the research project (travel, consumables, equipment etc.), tuition fees, and an annual, tax-free stipend of approximately £14,500 per year for UK nationals.

Statement of Research

Joint supervisors: Professor Alastair Hibbins, Professor Roy Sambles
Industry partner: QinetiQ

The primary objective of this studentship is to develop, fabricate and characterise novel materials, metasurfaces and metamaterials that can be used to reduce the amount of noise radiated by an object, in both airbourne and marine environments.

There has been a recent explosion in research on acoustic metamaterials and related concepts, including acoustic transformation (cloaking). Whilst the theoretical, and in many cases experimental, performance of these systems has been widely reported, many of these concepts either utilise idealised materials yet to be realised or suggest potential that far exceeds the realised performance.

This project will identify a number of promising concepts (e.g. pentamode materials, locally resonant sonic materials, 'acoustic blackholes', negative modulus materials perforated arrays, phononic glasses and thermoacoustic materials), and undertake simulation and experimentation tasks. in order to explore a wide range of acoustic materials, including locally resonant sonic materials (LRSMs). The successful applicant will characterise the potential performance of emergent disruptive acoustic technologies through the use of realisable materials and manufacturing techniques, and the measurement expertise and facilities at QinetiQ and the University of Exeter.

Funding

This award provides annual funding to cover UK tuition fees and a tax-free stipend. For students who pay UK tuition fees the award will cover the tuition fees in full, plus at least £14,500 per year tax-free stipend. The studentship will be awarded on the basis of merit for 3 and half years of full-time study to commence in September 2018.
