The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RÉSUMÉ

The 2D boundary problem arising in the study and analysis of characteristics of sound field radiated from the open end of the wedge-shaped waveguide is presented in the paper. The characteristic feature of the wave-guide geometry is that the end points of the boundary planes are situated on different distances from the top of the wedge. Major attention in this first part of the paper is focused on considering analytic structure of the wave fields and the principal features of solving algorithm. It is shown, that for the considered problems there is an indeterminacy in the form of analytical solution. By doing the analysis of numerical results the indeterminacy can be removed taking into account the minimizing volume of computations involved at their given accuracy.
