Global Love wave overtone measurements

Global Love wave overtone measurements

[1] Love wave phase velocities for fundamental and higher modes are difficult to measure because the different modes cannot easily be separated. Following Yoshizawa and Kennett (2002), we generate suites of path specific onedimensional shear wave velocity profiles using the Neighbourhood Algorithm of Sambridge (1999a). From this family of O(10) models both fundamental and higher mode phase velo...

From Global Mantle Wave Attenuation Measurements

We present the results of an analysis of global lateral variations in anelasticity of the upper mantle, as measured from very long period Rayleigh waves observed on the GEOSCOPE network. Four consecutive wave trains are used on each record to eliminate uncertainty on the amplitude at the source and to take into account, in a linear manner, focussing effects due to lateral variations in elastic ...

the acoustic waves propagation losses in solid solutions of Rare Earth in Ittrium Aluminium Garnets. Matrix were Y^^^AlcO..« found few times lower than that of YAG matrix. The high overtone bulk acoustic wave resonators made of Y-, Lu Alr01o were studies. The Q c .5—X X 2 I £. factor 1.5 2.0*10 at 3.5 4.0 GHz was experimentally found. 1 INTRODUCTION The practical interest to the investigation o...

Love Wave Biosensors: A Review

Integrated Love Wave Device Dedicated to Biomolecular Interactions Measurements in Aqueous Media

Mass-sensitive electro-acoustic devices such as surface acoustic wave (SAW)micro-balances, capable to operate with aqueous media are particularly favorable for thedevelopment of biosensors. Their dimensions and physical properties offer a large potentialin biological fluid investigations, especially for measuring physical phenomenon (massdeposition, adsorption, pressure...). In this work, we pr...
