Abstract

In the work the task of radiation of a at piston in a wedge-shaped waveguide is considered. The peculiarities of the radiation of a at piston into a wedge-shaped waveguide depending on the parametersof the task, namely, the angle of inclination of the wedge and the wave size of the piston, that is theratio of the piston length to the wavelength it emits, are investigated. The directional charts of a atpiston in a wedge-shaped waveguide at dierent angles of the wedge are calculated. It is shown that at acertain ratio between the wave size of the piston and the angle of inclination of the wedge, it is possibleto have a minimum in the directional chart along the axis of symmetry of the wedge. Calculations ofthe pressure modulus in the vicinity of the piston are performed, which illustrate how the failure in the directional chart in the direction of the waveguide axis is gradually formed.
