Show more >Acoustic radiation force (ARF) or torque (ART) can be derived by integrating the time-averaged linear and angular radiation stress tensor (the flux of momentum tensor) over a far-field standard spherical surface including an arbitrarily shaped target. Following this idea, there are three sets of independent original derivation on the ARF ([Silva, J. Acoust. Soc. Am. 130, 3541-3544 (2011)] and [Baresh et al., J. Acoust. Soc. Am. 133, 25-36 (2013)] based on the multipole expansion method, and [Sapozhnikov and Bailey, J. Acoust. Soc. Am. 133, 661-676 (2013)] based on the angular spectrum method); and two independent work on the ART ([Silva et al., EPL 97, 54003 (2012)] based on the multipole expansion method and [Gong and Bandoin, J. Acoust. Soc. Am. (under review; 2020)] based on the angular spectrum method). In this work, we formally establish the equivalence between the expressions obtained by these two methods with the relation of beam shape coefficients at different elementary waves of the field for both the force and torque. The differences between the existing formulas in the literature are indicated and explained. The respective advantages of each form are discussed.Show less >
