Abstract: | The solution is found for the problem of radiation of the surface Stoneley wave by a point harmonic force acting normally
to the interface between uniform solid and gaseous half-spaces. We consider the case where the sound velocity in the gas is
less than the Rayleigh-wave velocity on the surface of the solid. Expressions for the partial powers of the Stoneley wave
radiated into the solid and the gas are obtained. The dependences of these powers on the parameters of the contacting media
are analyzed. It is shown that if the velocities of the compressional and shear waves in the solid are significantly greater
than the sound velocity in the gas, then almost all power of the Stoneley wave is concentrated in the gas. If the velocity
of the Rayleigh wave in the solid half-space is close to the sound velocity in the gas, then the Stoneley-wave power radiated
into the solid can be greater than the power radiated in the gas.
