Radiation patterns from transducers on the Y face of LiNbO3 have been measured for propagation in several directions. It is demonstrated here that simple results may be obtained from a detailed Green's-function analysis which allow important practical information to be obtained, such as the Fresnel distance and far-field beam width as functions of the orientation of the transducer normal.
