A new approach to the analysis of the Smith-Purcell effect and its wave analogs has been proposed and implemented. It is based on the rigorous models of the exact absorbing conditions method and allows obtaining sufficiently reliable numerical data on the investigated processes in the conditions of a possible resonance waves scattering. Numerical experiments based on these models relieved and investigated in detail regimes with an anomalously high level of excitation of the outgoing waves that are of great interest both for theory and applications.
