Claim 13:
14. The apparatus of claim 9, wherein the length of the shockwave medium through which the emitted sinusoidal acoustic waves propagate is greater than or equal to L for at least one wavelength of the sinusoidal acoustic waves that the acoustic-wave generator is configured to emit, wherein L is determined by the following equation:, L
