Abstract :
The paper deals with the calculation of some resonances (frequency and width) in the case of an aluminium shell immersed in water. In some situations the resonance cannot be computed with a sufficient accuracy by the RST and we have developed a calculation based on the search in the complex frequency plane of the resonances. The results are also compared with those obtained from the phase gradient method
