Abstract
An electromagnetic pressure pulse source for generating focused pressure pulses as an electrically conductive membrane and a coil system which drives the membrane by rapidly displacing the membrane from the coil system. The coil system is formed by an annular array having a number of annular zones which can be individually activated to cause the generation of pressure pulses in variable chronological relation to each other, which permits the location of the focus of the resulting shockwave to be adjusted with a range, and/or the diameter of the focus to be changed.
