Acoustic cloaking transformations from attainable material properties

Urzhumov, Y; Ghezzo, F; Hunt, J; Smith, DR (New Journal of Physics, 2010-07-12)

We propose a general methodology and a set of practical recipes for the construction of ultra-broadband acoustic cloaks-structures that can render themselves and a concealed object undetectable by means of acoustic scattering. ...
Relaxation approach for the generation of inhomogeneous distributions of uniformly sized particles

Hunt, J; Kundtz, N; Landy, N; Smith, DR (Applied Physics Letters, 2010-07-12)

For many applications in gradient index devices and photonic crystals, it is necessary to be able to design semicrystalline distributions of particles where the lattice constant of the distribution is an arbitrary function ...
