In this paper, an explicit acoustical wave propagator technique is introduced to describe the time-domain evolution of acoustical waves in two-dimensional plates. This technique uses a combined scheme with Chebyshev polynomial expansion and Fast Fourier Transformation for implementation of the operation of the acoustical wave propagator. We also apply the acoustical wave propagator for studying dynamic stress in a step plate in time-domain.
