A new transducer beam model is developed for the generation of Rayleigh surface wave and Lamb plate waves by an angle beam transducer, which is one of the configurations commonly used for the generation of these wave types. The beam model is a fully 3‐D model that takes into account the fields generated by the transducer acting on the surface of a wedge. The model also accounts for the leaky wave nature of the surface or plate waves under the wedge surface through an explicitly defined leaky wave attenuation coefficient.
