    "abstract": "We report on parametric amplification in dynamic radiation force produced by\na bichromatic acoustic beam in a fluid. To explain this effect we develop a\ntheory taking into account the nonlinearity of the fluid. The theory is\nvalidated through an experiment to measure the dynamic radiation force on an\nacrylic sphere. Results exhibit an amplification of 66 dB in water and 80 dB in\nalcohol as the difference of the frequencies is increased from 10 Hz to 240\nkHz.",
