Fig.1a to 1c: Principles of shock wave generation. a. electrohydraulic, b. electromagnetic, c. piezoelectric. Extracted from [2].
Fig.2: Typical shock wave (pressure vs. time) in the focus F2 of an electrohydraulic shock wave system. Schematic representation of the pressure amplitude of the shock wave as a function of time. Positive pressure amplitude is followed by a tensile wave.
