Homogenization theory for periodic distributions of elastic cylinders embedded in a viscous fluid

Reyes Ayona, Edgar; Torrent Martí, Daniel; Sánchez-Dehesa Moreno-Cid, José (Acoustical Society of America, 2012-10)

A multiple-scattering theory is applied to study the homogenization of clusters of elastic cylinders distributed in a isotropic lattice and embedded in a viscous fluid. Asymptotic relations are derived and employed to ...
Noise control by sonic crystal barriers made of recycled materials

Sánchez-Dehesa Moreno-Cid, José; García Chocano, Víctor Manuel; Torrent Martí, Daniel; Cervera Moreno, Francisco Salvador; Cabrera García, Suitberto; Simon, Francisco (Acoustical Society of America, 2011-03)

A systematic study of noise barriers based on sonic crystals made of cylinders that use recycled materials like absorbing component is reported here. The barriers consist of only three rows of perforated metal shells filled ...
Tunable wideband bandstop acoustic filter based on two-dimensional multiphysical phenomena periodic systems

Romero García, Vicente; Sánchez Pérez, Juan Vicente; García-Raffi, L. M. (American Institute of Physics (AIP), 2011)

The physical properties of a periodic distribution of absorbent resonators is used in this work to design a tunable wideband bandstop acoustic filter. Analytical and numerical simulations as well as experimental validations ...
