Trapped Modes and Steered Dirac Cones in Platonic Crystals
R. C. McPhedran, A. B. Movchan, N. V. Movchan +2
This paper discusses the properties of flexural waves obeying the biharmonic equation, propagating in a thin plate pinned at doubly-periodic sets of points. The emphases are on the…
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.…
Transformation elastodynamics and cloaking for flexural waves
D. J. Colquitt, M. Brun, M. Gei +3
The paper addresses an important issue of cloaking transformations for fourth-order partial differential equations representing flexural waves in thin elastic plates. It is shown t…
