Transformation twinning to create isospectral cavities
Simon V. Lenz, Sébastien Guenneau, Bruce W. Drinkwater +2
Bounded domains have discrete eigenfrequencies/spectra, and cavities with different boundaries and areas have different spectra. A general methodology for isospectral twinning, whe…
Exploring high-frequency eddy-current testing for sub-aperture defect characterisation using parametric-manifold mapping
Robert R. Hughes, Bruce W. Drinkwater
Accurate characterisation of small defects remains a challenge in non-destructive testing (NDT). In this paper, a principle-component parametric-manifold mapping approach is applie…
Characterisation of carbon fibre-reinforced polymer composites through complex Radon-transform analysis of eddy-current data
R. R. Hughes, B. W. Drinkwater, R. A. Smith
Maintaining the correct fibre orientations and stacking sequence in carbon-fibre reinforced polymers (CFRP) during manufacture is essential for achieving the required mechanical pr…
Metamaterial bricks and quantization of meta-surfaces
Gianluca Memoli, Mihai Caleap, Michihiro Asakawa +3
Controlling acoustic fields is crucial in diverse applications such as loudspeaker design, ultrasound imaging and therapy, or acoustic particle manipulation. The current approaches…
Three-dimensional ultrasonic colloidal crystals
Mihai Caleap, Bruce Drinkwater
Colloidal assembly represents a powerful method for the fabrication of functional materials. In this article, we describe how acoustic radiation forces can guide the assembly of co…
Metamaterials: -classical dynamic homogenization
Mihai Caleap, Bruce W Drinkwater
Metamaterials are artificial composite structures designed for controlling waves or fields, and exhibit interaction phenomena that are unexpected on the basis of their chemical con…
