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…
Nested Bloch waves in elastic structures with configurational forces
Francesco Dal Corso, Domenico Tallarico, Natalia V. Movchan +2
Small axial and flexural oscillations are analyzed for a periodic and infinite structure, constrained by sliding sleeves and composed of elastic beams. A nested Bloch-Floquet techn…
Tilted resonators in a triangular elastic lattice: chirality, Bloch waves and negative refraction
Domenico Tallarico, Natalia V. Movchan, Alexander B. Movchan +1
We consider a vibrating triangular mass-truss lattice whose unit cell contains a resonator of a triangular shape. The resonators are connected to the triangular lattice by trusses.…
Blockage, trapping and waveguide modes for flexural waves in a semi-infinite double grating
Ian S. Jones, Natalia V. Movchan, Alexander B. Movchan
The paper presents a novel view on the scattering of a flexural wave in a Kirchhoff plate by a semi-infinite discrete system. Blocking and channelling of flexural waves are of spec…
Singular perturbations and cloaking illusions for elastic waves in membranes and Kirchhoff plates
I. S. Jones, M. Brun, N. V. Movchan +1
A perturbation approach is used for analysis of a near-cloak in shielding a finite scatterer from an incident flexural wave. The effect of the boundary conditions on the interior s…
Active cloaking of finite defects for flexural waves in elastic plates
J. O'Neill, O. Selsil, R. C. McPhedran +2
We present a new method to create an active cloak for a rigid inclusion in a thin plate, and analyse flexural waves within such a plate governed by the Kirchhoff plate equation. We…
