REFLECTION AND REFRACTION OF HARMONIC WAVES AT THE BOUNDARIES OF A POROUS MEDIUM SATURATED WITH A BUBBLY LIQUID

Refl ection and transmission of acoustic waves at the interface between water and a porous medium saturated with bubbly liquid and the porous medium saturated with a bubbly liquid–water interface at normal incidence of these waves on the indicated interfaces have been studied theoretically. It is shown that there exists a range of frequencies, for which refl ection of acoustic waves from the interface between water and a porous medium saturated with bubbly liquid is similar to refl ection of these waves from a free surface, and for refl ection of acoustic waves from the medium saturated with bubbly liquid/water interface it is similar to refl ection from a rigid wall
