Abstract :
The reflection of a bounded acoustic beam with an even-ordered polynomial cross section from a fluid-porous body plane interface is studied. The porous medium is considered as a two-component mixture of solid and liquid phases with variable porosity parameter. An analysis of the formation process of the reflected beam profile with the incidence angle of the primary wave beam near the critical angles of the surface acoustic waves in the porous material is performed
