Time-domain calculation of acoustical wave propagation in discontinuous media using acoustical wave propagator with mapped pseudospectral method

The acoustical Wave Propagator (AWP) scheme involves an effective time-domain calculation of sound propagation using the combination of Chebyshev polynomial expansion and the Fourier pseudospectral method. The accuracy of this scheme degrades when the media has discontinuities due to the well-known...
