Scattering from a non-linear structured interface
Domenico Tallarico, Natalia V. Movchan, Alexander B. Movchan
We review the scattering from non-linear interfaces containing buckling elastic beams. An illustrative example is discussed here of scattering of linear elastic pressure waves from…
Platonic Localisation: One Ring to Bind Them
A. B. Movchan, R. C. McPhedran, G. Carta +1
In this paper, we present an asymptotic model describing localised flexural vibrations along a structured ring containing point masses or spring-mass resonators in an elastic plate…
Vibrations and elastic waves in chiral multi-structures
Michael Nieves, Giorgio Carta, Ian Jones +2
We develop a new asymptotic model of the dynamic interaction between an elastic structure and a system of gyroscopic spinners that make the overall multi-structure chiral. An impor…
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…
Semi-infinite herringbone waveguides in elastic plates
Stewart G Haslinger, Ian S Jones, Natasha V Movchan +1
The paper includes novel results for the scattering and localisation of a time-harmonic flexural wave by a semi-infinite herringbone waveguide of rigid pins embedded within an elas…
Floquet-Bloch waves in periodic networks of the Rayleigh beams: honeycomb systems, dispersion degeneracies and structured interfaces
L. Cabras, A. B. Movchan, A. Piccolroaz
The paper addresses novel dispersion properties of elastic flexural waves in periodic structures which possess rotational inertia. The structure is represented as a lattice, whose…
