Abstract
A mathematical description for ultrasound transduction with EMATs in an electrically conductive, ferromagnetic half space has been used to calculate the acoustic field of bulk waves and Rayleigh waves generated by EMATs consisting of one or two current lines. Results for SV- and SH-waves are presented and compared to experimental directivity patterns. The mathematical formalism can be applied to calculate transfer impedances, radiation impedances or insertion losses when the values for the material parameters which are used in the theory have been determined.
