    "abstract": "We present an approach to numerically solving the time-dependent Schroedinger\nequation and other parabolic equations by the split-step technique with fast\nFourier transform, which suppresses the backreflection of waves from the grid\nboundaries with any specified accuracy. Most importantly, all known methods\nwork well only for a narrow region of incident waves spectrum, and the proposed\nmethod provides absorption of any wave whose length is large enough in\ncomparison with the size of absorption region.",
