Accounting for the spatial observation window in the two-dimensional Fourier transform analysis of shear wave attenuation

Recent measurements of shear wave propagation in viscoelastic materials have been analyzed by constructing the two-dimensional Fourier transform (2DFT) of the shear wave signal and measuring the phase velocity c(ω) and attenuation α(ω) from the peak location and full width at half maximum (FWHM) of...
