Congratulations to CDT PGR Joseph Beadle, who submitted his thesis last week.
Joseph was supervised by Prof. J. R. Sambles and Prof. A.P. Hibbins, and his PhD project was entitled: ‘An exploration of acoustic metasurfaces’. The aim was to experimentally explore the effect that structuring surfaces had on the near-field acoustic surface waves. The project involved both airborne and underwater acoustics. He published two papers whilst at Exeter: ‘The acoustic phase resonances and surface waves supported by a compound rigid grating’ & ‘Broadband, slow sound on a glide-symmetric meander-channel surface’.
During this time he presented at international conferences such as: ASP DFD (American physics society – division of fluid dynamics) in Denver, USA (2017), and Underwater Acoustics Conference and Exhibition, Hersonissou, Greece (2019). Joseph has been working as a member of TEAM-A based in QinetiQ, where he is expanding on his PhD work and investigating novel underwater metamaterials for the absorption and manipulation of acoustic energy.
