Composite absorbing potentials
arXiv:quant-ph/9805035 · doi:10.1103/PhysRevLett.80.5469
Abstract
The multiple scattering interferences due to the addition of several contiguous potential units are used to construct composite absorbing potentials that absorb at an arbitrary set of incident momenta or for a broad momentum interval.
