Edge Waves and Transmissions for Temporal Laminates and Imperfect Chiral Interfaces
A. B. Movchan, N. V. Movchan, I. S. Jones +2
The analysis of wave patterns in a structure which possesses periodicity in the spatial and temporal dimensions is presented. The topic of imperfect chiral interfaces is also consi…
Wave polarisation and dynamic degeneracy in a chiral elastic lattice
G. Carta, I. S. Jones, N. V. Movchan +1
This paper addresses fundamental questions arising in the theory of Bloch-Floquet waves in chiral elastic lattice systems. This area has received a significant attention in the con…
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…
Edge waves and localisation in lattices containing tilted resonators
Domenico Tallarico, Alessio Trevisan, Natalia V. Movchan +1
The paper presents the study of waves in a structured geometrically chiral solid. A special attention is given to the analysis of the Bloch-Floquet waves in a doubly periodic high-…
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.…
Propagation and filtering of elastic and electromagnetic waves in piezoelectric composite structures
Domenico Tallarico, Natalia V. Movchan, Alexander B. Movchan +1
In this article we discuss the modelling of elastic and electromagnetic wave propagation through one- and two-dimensional structured piezoelectric solids. Dispersion and the effect…
Parabolic Metamaterials and Dirac Bridges
D. J. Colquitt, N. V. Movchan, A. B. Movchan
A new class of multi-scale structures, referred to as `parabolic metamaterials' is introduced and studied in this paper. For an elastic two-dimensional triangular lattice, we ident…
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…
Experimental and analytical insights on fracture trajectories in brittle materials with voids
D. Misseroni, A. B. Movchan, N. V. Movchan +1
Analytical models have been developed for fracture propagation over the last several decades and are now considered with renewed interest; the range of their applicability varies f…
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…
Localisation for a line defect in an infinite square lattice
D. J. Colquitt, M. J. Nieves, I. S. Jones +2
Localised defect modes generated by a finite line defect composed of several masses, embedded an infinite square cell lattice, are analysed using the linear superposition of Green'…
