Acoustic radiation force is a physical phenomenon resulting from the interaction of an acoustic wave with an obstacle placed along its path. Generally, the force exerted on the obstacle is evaluated by integrating the acoustic radiation pressure (due to the presence of the sonic wave) over its time-varying surface. The magnitude of the force exerted by an acoustic plane wave at any given location can be calculated as: where F is the force in kg/(s²cm²), α is the absorption coefficient in Np/cm, I is the temporal average intensity of the acoustic wave at the given location in W/cm², and c is the speed of sound in the medium in cm/s.
