Robust collimated beaming in 3D acoustic sonic crystals
A. L. Vanel, M. Dubois, C. Tronche +11
We demonstrate strongly collimated beaming, at audible frequencies, in a three-dimensional acoustic phononic crystal where the wavelength is commensurate with the crystal elements;…
Acoustic topological circuitry in square and rectangular phononic crystals
Nicolas Laforge, Richard Wiltshaw, Richard V. Craster +6
We systematically engineer a series of square and rectangular phononic crystals to create experimental realisations of complex topological phononic circuits. The exotic topological…
Experimental observations of topologically guided water waves within non-hexagonal structures
Mehul P. Makwana, Nicolas Laforge, Richard V. Craster +4
We investigate symmetry-protected topological water waves within a strategically engineered square lattice system. Thus far, symmetry-protected topological modes in hexagonal syste…
Low frequency acoustic stop bands in cubic arrays of thick spherical shells with holes
Guillaume Dupont, Alexander Movchan, Stefan Enoch +1
We analyse the propagation of pressure waves within a fluid filled with a three-dimensional array of rigid coated spheres (shells). We first draw band diagrams for corresponding Fl…
Dykes for filtering ocean waves using c-shaped vertical cylinders
Guillaume Dupont, Fabien Remy, Olivier Kimmoun +3
The present study investigates a way to design dykes which can filter the wavelengths of ocean surface waves. This offers the possibility to achieve a structure that can attenuate…
Invisibility carpet in a channel with a structured fluid
Guillaume Dupont, Sebastien Guenneau, Stefan Enoch
We first note it is possible to construct two linear operators defined on two different domains, yet sharing the same spectrum using a geometric transform. However, one of these tw…
