Amplitude coda of classical waves in disordered media
arXiv:cond-mat/0205014 · doi:10.1103/PhysRevE.65.045604
Abstract
The propagation of classical waves in the presence of a disordered medium is studied. We consider wave pulses containing a broad range of frequencies in terms of the configurationally averaged Green function of the system. Damped oscillations in the time-dependent response trailing behind the direct arrival of the pulse (coda) are predicted, the periods of which are governed by the density of scatterers.
