Spatial-temporally resolved high-frequency surface acoustic waves on silicon investigated by femtosecond spectroscopy
(American Institute Of Physics, 2012-06)
Various types of surface acoustic waves are generated by femtosecond pulses on bulk silicon with aluminium stripe transducers. Rayleigh and leaky longitudinal surface acoustic wave modes are detected in the time domain for ...
A methodology for the analysis of the rayleigh-wave ellipticity
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2013)
In this paper, a comprehensive explanation of the analysis (filtering and inversion) of the Rayleigh-wave ellipticity is performed, and the use of this analysis to determine the local crustal structure beneath the recording ...
THE OUTGOING TIME-HARMONIC ELASTIC WAVE IN A HALF-PLANE WITH FREE BOUNDARY
(SIAM PUBLICATIONS, 2011)
Under a time-harmonic assumption, we prove existence and uniqueness results for the outgoing elastic wave in an isotropic half-plane, where the source is given by a local normal stress excitation of the free boundary. This ...

Supressão do ruído de rolamento superficial utilizando a transformada Curvelet
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2009-05-08)
Among the many types of noise observed in seismic land acquisition there is one produced by surface waves called Ground Roll that is a particular type of Rayleigh wave which characteristics are high amplitude, low frequency ...
Crustal model of the Southern Central Andes derived from ambient seismic noise Rayleigh-wave tomography
(2018)
The distribution and the interconnection of magmatic bodies beneath volcanic arcs is key to asses volcanic hazard and eruptive processes taking place at convergent margins. We use ambient seismic noise Rayleigh-wave ...
