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…
