Abstract

It was considered a beamed sound field for a planar matrix disk- and square-shaped oscillator. The radiation pressure in focal region is calculated as a sum of contributions of separate discrete sources considering their focusing. There is given estimation of an axial pressure distribution for different values of focusing index. The dependence of focal region extent and width on aperture size of disk oscillator was analyzed. There is cited an example for forming of a spread sound beam of disk matrix
