Abstract

The paper investigates the possibility of using combinations of two options of wave fields conjugation (the conjugation by points and the root mean square approximation) in the method of partial domains using the example of solving the problem of piston radiation in a finite wedge-shaped waveguide. It is shown that the option of using the root mean square approximation is the best, while the use of the conjugation by points of fields generally simplifies the calculation of the problem. The choice of the required calculation combination depends on the problem under consideration, and it is possible that the combined calculation option may lead to a better solution to the problem in terms of fulfilling the law of energy conservation or field conjugation conditions.
