dc.description.abstract <p>In earlier work [1,2] a simple idea for self-focusing of a linear array has been used for Rayleigh and Lamb waves. The self-focusing procedure automatically moves the focal region of the array towards the defect that produces the largest backscattered signal by adjusting the excitation times of the elements of the array. Experimental results demonstrate the ability to self-focus Rayleigh waves and Lamb waves on defects in thick slabs and thin sheets. The aim of this paper is to supplement the experimental results with a measurement model of the self-focusing of surface waves. A model for the surface wave generated by a single element of the linear array has been developed. The field generated by the entire array has been simulated by using superposition.</p>
