The strange case of Negative Reflection
Bibinur Meirbekova, Lorenzo Morini, Michele Brun +1
In this paper we show for the first time the phenomenon of negative reflection in a simple mechanical structure. The latter is a grating of fixed inclusions embedded in a linear el…
Platonic crystal with low-frequency locally resonant snail structures. Wave trapping, transmission amplification and shielding
M. Morvaridi, G. Carta, M. Brun
We propose a new type of platonic crystal. The proposed microstructured plate includes snail resonators with low-frequency resonant vibrations. The particular dynamic effect of the…
A class of auxetic three-dimensional lattices
Luigi Cabras, Michele Brun
We propose a class of auxetic three-dimensional lattice structures. The elastic microstructure can be designed in order to have omni-directional Poisson's ratio arbitrarily close t…
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…
Auxetic two-dimensional lattice with Poisson's Ratio arbitrarily close to -1
L. Cabras, M. Brun
In this paper we propose a new lattice structure having macroscopic Poisson's ratio arbitrarily close to the stability limit -1. We tested experimentally the effective Poisson's ra…
Transformation cloaking and radial approximations for flexural waves in elastic plates
M. Brun, D. J. Colquitt, I. S. Jones +2
It is known that design of elastic cloaks is much more challenging than the design idea for acoustic cloaks, cloaks of electromagnetic waves or scalar problems of anti-plane shear.…
