DEVICE USED FOR THE LOCALIZED DESTRUCTION OF SOFT STRUCTURES USING NEGATIVE PRESSURE ELASTIC WAVES

摘要

the apparatus comprises a source of disclosure materials.the surface of elastic oscillations over a short with ridges, and means for focusing the negative swings on the target.the oscillation frequency is adjusted between 0.3 and 10 mhz, and the length of the wave train, with values between 1 and us 1.the rate of fire is from a few hz to 2 or 3 khz.
