Acoustic Bessel-like beam formation by an axisymmetric grating
N. Jiménez, V. Romero-García, R. Picó +5
We report Bessel-like beam formation of acoustic waves by means of an axisymmetric grating of rigid tori. The results show that the generated beam pattern is similar to that of Bes…
Propagating and evanescent properties of double-point defects in Sonic Crystals
V. Romero-García, J. V. Sánchez-Pérez, and L. M. Garcia-Raffi
Complex Band Structures and Multiple Scattering Theory have been used in this paper to analyze the overlapping of the evanescent waves localized in point defects in Sonic Crystals.…
Analysis of the wave propagation properties of a periodic array of rigid cylinders perpendicular to a finite impedance surface
V. Romero-García, J. V. Sánchez-Pérez, L. M. Garcia-Raffi
The effect of the presence of a finite impedance surface on the wave propagation properties of a two-dimensional periodic array of rigid cylinders with their axes perpendicular to…
Analytical model to predict the effect of a finite impedance surface on the propagation properties of a 2D Sonic Crystal
V. Romero-García, J. V. Sánchez-Pérez, L. M. Garcia-Raffi
The use of Sonic Crystals as environmental noise barriers has certain advantages from the acoustical and the constructive point of view with regard to conventional ones. One aspect…
Tunable wideband bandstop acoustic filter based on 2D multi-physical phenomena periodic systems
V. Romero-García, J. V. Sánchez-Pérez, L. M. Garcia-Raffi
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 simu…
