A new type of the monolithic acoustic scanner based on a near-surface quasicomposite two-dimensional array, implemented in the solid elastic substrate was proposed. It provides a simple means of focusing and scanning a beam of acoustic waves, radiated into the depth of the elastic solid substrate. A chirped surface acoustic wave is converted into a focused bulk wave by scattering from an array composed of a 2D periodic system of regions with varying material parameters, located at the surface of a surface acoustic waves substrate. In the paper, a simple numerical simulation model is presented to analyse the influences of the dynamical and geometrical parameters of the surface structure, as well as the influences of incident surface acoustic waves signal profile on the focal distribution.
