Circuit Design by Digital Computer

The phase and amplitude distribution of elastic surface waves on piezoelectric substrates may be measured by means of an electrostatic surface probe of the type originally dcmonstrated by Kichardson and Kino ( 11 . An improved version of the electrostatic probe is described and the opera- tion of this device is analyzed. Two unique display techniques allow rapid and straighforward analysis of wavefront distortion for surface waves. Measurements of the propagation character- istics ofZ-directed waves on Y-cut lithium niobate are presented.
