• Modeling acoustic wave propagation in heterogeneous attenuating media using decoupled fractional Laplacians (2014, methodology): “…coefficient α and the phase velocity are calculated by the amplitude spectral ratio in decibels/meter and the phase change at each frequency (Buttkus, 2000; Treeby and Cox, 2010): αðωÞ ¼ −20 log10 A2 A1 ∕d; (20) cðωÞ ¼ ωd ϕ1 − ϕ2 ; (21) where A1;2 are the amplitude spectra at two…”
