    "abstract": "The subject of this paper is to present a theory for the dynamic radiation\nforce produced by dual-frequency ultrasound beams in lossless and\nnon-dispersive fluids. A formula for the dynamic radiation force exerted on a\nthree-dimensional object by a dual-frequency beam is obtained stemming from the\nfluid dynamics equations. Dependence of the dynamic radiation force to\nnonlinear effects of the medium is analyzed. The developed theory is applied to\ncalculate the dynamic radiation force exerted on solid elastic (brass and\nstainless steel) spheres by a low-amplitude dual-frequency plane wave. The\ndynamic radiation force is calculated by solving the dual-frequency plane wave\nscattering problem for solid elastic spheres. Results show that the dynamic\nradiation force on the analized spheres presents fluctuations similar to those\npresent in the static radiation force. Furthermore, analysis of the static and\nthe dynamic radiation forces on the stainless steel sphere shows that they have\napproximately the same magnitude.",
