Nearly constant Q models of the generalized standard linear solid type and the corresponding wave equations

Time-domain seismic forward and inverse modeling for a dissipative medium is a vital research topic for investigating the attenuation structure of the earth. Constant [Formula: see text], also called the frequency independence of the quality factor, is a common assumption for seismic [Formula: see text] inversion. We have developed first- and second-order nearly constant [Formula: see text] dissipative models of the generalized standard linear...
