Non-uniform time-stepping in k-space pseudospectral time domain models of acoustic propagation
Matthew J. King, B. E. Treeby, B. T. Cox
Non-uniform time stepping in acoustic propagation models can be used to preserve accuracy or reduce computational cost for an acoustic simulation with a wave front propagating thro…
