This work presents a detailed analysis of complex absorbing potentials employed to eliminate reflection or wrap-around of wave packets at numerical grid boundaries. In particular, a limiting value for the maximum propagation time step is derived, beyond which the complex potential may introduce massive errors and the Chebyshev propagation scheme is found to fail.
