EPSRC CDT in Metamaterials/Prosperity Partnership TEAM-A (PhD Studentship): Disruptive Technologies for Acoustic Noise Reduction

University of Exeter - Centre of Doctoral Training in Metamaterials (XM2)

Statement of Research

Joint supervisors: Professor Alastair HibbinsProfessor Roy Sambles
Industry partnerQinetiQ

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.

This studentship is part of the Centre of Doctoral Training in Metamaterials. Please see all fully funded opportunities.
