Abstract

The focus is laid on analyzing radiated sound field of rectangled plunger. The sound pressure distribution in three_dimensional space has been calculated out by use of Reigly_integration, and amplitude distribution is plotted out by numerical method. Analysis is made of directivity of wave steering. It shows that wave directivity is influenced by plunger size or wave frequency. All this 2D arrays. The analytical pressure distribution for the beam focusing is then obtained by using the Huygen′s principle. This expression is useful for studying the far field characteristics of the beam focused. The directivities are quantitatively analyzed.
