Some features of non-compensated piezoceramic antenna radiation in borehole

The possibility to get impedance boundary conditions for diffraction problem relating to non-compensated piezoceramic antenna radiation in borehole is studied. The method of equivalent electromechanical circuits is used to determine dependences between characteristics of the antenna and radiation field. It is shown that the optimal conditions of acoustic energy transmission from borehole into a massif considerably differ from similar conditions when ideal boundary conditions are applied.
