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

The Wiener-Hopf method is used to consider the resonant case of diffraction of TM mode incident on a segment of an ideally conducting cylinder of radius coaxially located inside an infinite waveguide of radius. The boundary value problem is first reduced to the paired integral equations and then to a system of linear algebraic equations. The parameters of eigenoscillations of an open cylindrical resonator are determined from the condition that the determinant of the system of algebraic equations is equal to zero.
