Features of Ultrasonic Testing with the Use of Electromagnetic Acoustic Transducers

V. E. Chabanov, V. A. Zhukov

The main problems arising at electromagnetic acoustic transducer (EMAT) construction and ways of their solutions are described. Theoretical apparatus is given for numerical experiments and comparison of different EMAT constructions. It is shown how electronic channel of EMAT excitation and reception as well as the coils used affect the spatial and time parameters of radiated and received ultrasonic signals.
