USING TWO OPTIONS FOR CONJUGATING WAVE FIELDS IN THE METHOD OF PARTIAL DOMAINS

Abstract

The paper considers the use of two options of conjugation of wave fields in the method of partial domains: the first is the conjugation of wave fields in the sense of the root mean square approximation, the second is the pointwise conjugation of wave fields. A solution is obtained for the problem of radiation from one or two flat pistons into a wedge-shaped waveguide. It is shown that with the same number of modes in partial domains, the version of the root mean square approximation is more accurate. A quite acceptable calculation accuracy was obtained for the option of pointwise conjugation of fields at a certain value of the wave distance between the nodal points.
