Abstract
We analyze the possibility for obtaining relevant boundary conditions of the diffraction problem of radiation of an extended piezoceramic antenna in a borehole. The method of equivalent electromechanical circuits is used to search for relationships between the characteristics of the antenna and the radiated fields of elastic vibrations. It is shown that the optimal conditions for transfer of acoustic energy from a borehole to a massif in the considered case drastically differ from similar conditions corresponding to ideal boundary conditions. The expressions for the potentials of displacements in the massif are obtained. Experimental data confirming the analytical results are adduced.
