Patent ID: 8596129

Claim:
An EMUS transducer system for producing linearly polarized transverse waves having a variably predeterminable polarization direction within a test specimen containing at least ferromagnetic material portions and having a test specimen surface, comprising: a magnetization unit for producing a magnetic field orientated parallel to the test specimen surface within the test specimen, at least one HF coil on the test specimen surface for producing or detecting a HF field combined with the magnetic field orientated parallel to the test specimen surface within the test specimen, the magnetization unit including at least three magnetization bodies spatially separated from one another and which are positionable on the test specimen surface for introducing a magnetic field having a predeterminable magnetic flux into the test specimen; and means for changing the magnetic flux emanating from at least one of magnetization bodies to vary a spatial direction of the magnetic field relative to the test specimen surface within the test specimen.
