Design of a resonant Luneburg lens for surface acoustic waves (2020)
Journal Article
Fuentes-Domínguez, R., Yao, M., Colombi, A., Dryburgh, P., Pieris, D., Jackson-Crisp, A., …Clark, M. (2021). Design of a resonant Luneburg lens for surface acoustic waves. Ultrasonics, 111, Article 106306. https://doi.org/10.1016/j.ultras.2020.106306

© 2020 In this work we employ additive manufacturing to print a circular array of micropillars on an aluminium slab turning its top surface into a graded index metasurface for surface acoustic waves (SAW). The graded metasurface reproduces a Luneburg... Read More about Design of a resonant Luneburg lens for surface acoustic waves.

Characterising the size and shape of metallic nano-structures by their acoustic vibrations (2020)
Journal Article
Fuentes-Domínguez, R., Naznin, S., Marques, L., Pérez-Cota, F., Smith, R. J., & Clark, M. (2020). Characterising the size and shape of metallic nano-structures by their acoustic vibrations. Nanoscale, 12(26), 14230-14236. https://doi.org/10.1039/d0nr03410j

© 2020 The Royal Society of Chemistry. The characterisation of metallic nano-structures is of great importance as their optical properties are strongly dependent on their size and shape. Inaccurate size or shape characterisation can result in mislead... Read More about Characterising the size and shape of metallic nano-structures by their acoustic vibrations.

Determining the crystallographic orientation of hexagonal crystal structure materials with surface acoustic wave velocity measurements (2020)
Journal Article
Lain'e, S. J., Dryburgh, P., Smith, R. J., Marrow, P., Lainé, S. J., Sharples, S. D., …Li, W. (2020). Determining the crystallographic orientation of hexagonal crystal structure materials with surface acoustic wave velocity measurements. Ultrasonics, 108, Article 106171. https://doi.org/10.1016/j.ultras.2020.106171

© 2020 Throughout our engineered environment, many materials exhibit a crystalline lattice structure. The orientation of such lattices is crucial in determining functional properties of these structures, including elasticity and magnetism. Hence, too...

Apparent attenuation by opto-acoustic defocus in phonon microscopy (2020)
Journal Article
Fuentes-Domínguez, R., La Cavera, S., Pérez-Cota, F., La Cavera III, S., Naznin, S., Fuentes-Dominguez, R., …Clark, M. (2020). Apparent attenuation by opto-acoustic defocus in phonon microscopy. Photoacoustics, 19, Article 100180. https://doi.org/10.1016/j.pacs.2020.100180

© 2020 The Author(s) Understanding the mechanical properties of biological cells is a challenging problem for the life sciences partly because there are limited methods for mapping elasticity with high resolution. Phonon microscopy is a form of Brill... Read More about Apparent attenuation by opto-acoustic defocus in phonon microscopy.
