| Abstract: | In this paper the convolution-impulse response approach is briefly introduced.In order to show the abilities of the approach, several numerical examples of the array near-field are given,in which the cases of pure beam focusing and beam focusing with deflection are considered.The results show that this approach appears to be an effective tool not only for a qualitative analysis of the near-field,but also for the prediction of the sound field. |

| Keywords: | linear phased array convolution-impulse method pure focusing focusing with deflection |
