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 reflection 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 reflection of a transverse wave occurs. Conditions have been determined with which the reflection of the wave as that from a rigid wall occurs. [ABSTRACT FROM AUTHOR]
