OFF-NORMAL INCIDENCE OF A SOUND WAVE ON THE BOUNDARY "BUBBLE LIQUID–POROUS MEDIUM SATURATED WITH BUBBLE LIQUID"

A theoretical study has been made of the refl ection and refraction of a harmonic sound wave on the boundary "bubble liquid–porous medium saturated with bubble liquid." It has been established that in the case of incidence of such a wave on the indicated boundary at a certain angle, the total internal refl ection of a transverse wave occurs. Conditions have been determined with which the refl ection of the wave as that from a rigid wall occurs
