Abstract

Based on the analytic expressions for the radiated field of a circular concave piston given by Hasegawa et al an integral for calculation of the radiation force on a plane absorbing target in a spherically focused field is derived A general relation between acoustic power P and normal radiation force F n is obtained under the condition of kr ≫ 1 Numerical computation is carried out by using the symbolic computation program for practically focused sources and absorbing circular targets The results show that for a given source there is a range of target positions where the radiation force is independent of the target’s position under the assumption that the contribution of the acoustic field behind the target to the radiation force can be neglected The experiments are carried out and confirm that there is a range of target positions where the measured radiation force is basically independent of the target’s position even at high acoustic power up to 700 W It is believed that when the radiation force method is used to measure the acoustic power radiated from a focused source the size of the target must be selected in such a way that no observable sound can be found in the region behind the target
