Abstract
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, a magnetization unit produces a magnetic field orientated parallel to the test specimen surface within the test specimen. At least one HF coil on the test specimen surface produces or detects a HF field combined with the magnetic field orientated parallel to the test specimen surface within the test specimen. The magnetization unit includes at least three magnetization bodies spatially separated from one another to introduce a magnetic field into the test specimen. The magnetic flux emanating from at least one of magnetization bodies a spatial direction relative to the test specimen surface is varied.
