Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

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.
