Abstract
The waves generated on a determined area of a cylindrical shell and with an angle of incidence α are propagated parallel with the axis of this cylinder. Then, the radiation, in the far field, can be observed in the end of this shell with a quasi-harmonic method. The axial displacement is analysed and the use of the Rayleigh integral allows us to determine the radiated pressure. The results of the theoretical calculation are in agreement with the results of experiments.
