Summary:Lamb wave excitation by the wedge-shaped ultrasonic phase array transducer was investigated by the finite element (FEM) method. Maps of the excitation efficiency were obtained for the plates of three different types of glass. Get maps effectiveness of excitation of Lamb waves. The conditions for preferential excitation of one mode of Lamb. Influences of three different liquid layers and the dependence of the aperture of the transducer were investigated.
