In earlier papers [1, 2], the authors have presented theoretical and experimental results for the generation of focused surface wave motion by a linear array of surface wave transducers. It was shown that a single element generates a beam with an opening angle of approximately 20°, and a cross section which can be accurately represented by a Gaussian distribution of the normal displacements. For an eight-element array, the focused beam was modeled by superposition considerations. Comparisons of theoretical and experimental results, where the latter were obtained by the use of a laser interferometer [3], showed excellent agreement for the normal displacement both along a radial line and across the width of the beam. The transducer array with a center frequency of 5MHz was used for surface-defect detection, whereby the focal region was automatically adjusted to the defect location [4].
