Abstract

Using stepped arrays of transducers, the direction of propagation of surface acoustic waves can be controlled by varying the input frequency. This effect has applications in maintaining the optimum Bragg angle in acousto-optic devices for integrated optics. The measured beam-steering angle for a given frequency change follows the theory of Pinnow, where anisotropy effects are taken into account.
