A State-Space Framework for trivial and Topological Metamaterial Stochastic Analysis
Luiz Henrique Marra da Silva Ribeiro, Abhilash Sreekumar, Vinícius Fonseca Dal Poggetto +4
Topological phononic crystals and elastic metamaterials support edge states defined by global topological invariants, offering a route toward vibration-control and wave-guiding dev…
Weak scattering formulation for flexural waves in thin elastic plates with point-like resonators
Mario Lázaro, Marc Martí-Sabaté, Richard V. Craster +1
A theoretical study on the weak scattering formulation for flexural waves in thin elastic plates loaded by point-like resonators is reported. Our approach employs the Born approxim…
Wave propagation in beams with multiple resonators: conditions for weak scattering and the Born approximation
Mario Lázaro, Richard Wiltshaw, Richard V. Craster +1
This work reports the conditions under which weak scattering assumptions can be applied in a beam loaded by multiple resonators supporting both longitudinal and flexural waves. The…
Formation of high-order acoustic Bessel beams by spiral diffraction gratings
Noé Jiménez, Rubén Picó, Víctor Sánchez-Morcillo +3
The formation of high-order Bessel beams by a passive acoustic device consisting of an Archimedes' spiral diffraction grating is theoretically, numerically and experimentally repor…
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…
Wave focusing using symmetry matching in axisymmetric acoustic gradient index lenses
V. Romero-García, A. Cebrecos, R. Picó +3
The symmetry matching between the source and the lens results of fundamental interest for lensing applications. In this work we have modeled an axisymmetric gradient index (GRIN) l…
Enhancement of sound in chirped sonic crystals
V. Romero-García, R. Picó, A. Cebrecos +2
We propose and experimentally demonstrate a novel mechanism of sound wave concentration based on soft reflections in chirped sonic crystals. The reported controlled field enhanceme…
Formation of collimated sound beams by three-dimensional sonic crystals
A. Cebrecos, V. Romero-Garcia, R. Pico +4
A theoretical and experimental study of the propagation of sound beams in- and behind three-dimensional sonic crystals at frequencies close to the band edges is presented. An effic…
