Analysis was performed of information sources over the recent years, which give the results of theoretical and model studies of electromagneto-acoustic method of excitation and reception of ultrasonic waves of body, surface and normal types. It is found that comprehensive theoretical and model studies allow establishing more effective principles of design of various purpose EMA transducers. The possibility of development of EMAT with phased arrays, as well as devices with pulsed sources of polarizing magnetic field is shown. 25 References, 4 Figures.
