Analysis of axial waves in visco-elastic complex structural-acoustic systems: Theory and experiment
J. A. Rojas, A. Morales, L. Gutiérrez +4
An experimental and theoretical study of the spectral response of coupled visco-elastic bars subject to axial oscillations is done. Novel closed formulas for the envelope function…
Anderson Localization Phenomenon in One-dimensional Elastic Systems
R. A. Mendez-Sanchez, L. Gutierrez, A. Morales +3
The phenomenon of Anderson localization of waves in elastic systems is studied. We analyze this phenomenon in two different set of systems: disordered linear chains of harmonic osc…
Anderson Localization in Disordered Vibrating Rods
J. Flores, L. Gutiérrez, R. A. Méndez-Sánchez +3
We study, both experimentally and numerically, the Anderson localization phenomenon in torsional waves of a disordered elastic rod, which consists of a cylinder with randomly space…
Building and Destroying Symmetry in 1-D Elastic Systems
J. Flores, G. Monsivais, P. Mora +4
Locally periodic rods, which show approximate invariance with respect to translations, are constructed by joining unit cells. The spectrum then shows a band spectrum. We then b…
Wannier-Stark ladders in one-dimensional elastic systems
L. Gutierrez, A. Diaz-de-Anda, J. Flores +3
The optical analogues of Bloch oscillations and their associated Wannier-Stark ladders have been recently analyzed. In this paper we propose an elastic realization of these ladders…
Avoided Band Crossing in Locally Periodic Elastic Rods
R. A. Mendez-Sanchez, A. Morales, J. Flores
Avoided band crossings have been studied theoretically and it has been shown that they can provide a tunning of the metal-insulator transition. Here we present an experimental exam…
