Multiple refraction switches realized by stretching elastomeric scatterers in sonic crystals
The effect of out-of-plane pre-stretch on the 2D sonic crystal with stretchable elastomeric scatterers is explored. The hyperelastic scatterers are characterized by a compressible neo-Hookean model. The Dirichlet-to-Neumann (DtN) map is adopted to obtain the band structure and equi-frequency contour...
