A numerical method for the accurate evaluation of a propagator in a grid space is presented. The algorithm is stable and accurate up to a microscopically significant long time ( = 100 ps for proton tunneling processes). The procedure is achieved by first initializing the small time propagator to be

This paper applies the acoustical wave propagator technique to wave packet propagation in a one-dimensional stepped beam. The time-domain analytical solutions of this structure subjected to an initial-value problem with the specific Gaussian waveform were derived and compared with the predicted resu

In this paper, we explore algorithms for an evaluation of the space transformation factor (STF) in the application of the transformed-space nonuniform pseudo-spectral time-domain (TSNU-PSTD) scheme. We apply these algorithms to both typical propagation problems and scattering analyses. Before implem
