Abstract
An electromechanical device for generating elastic waves in a material medium such as the subsoil in a frequency range where the wavelengths of the waves generated are great in view of the dimensions of the device, and method of implementation. The device comprises one or more vibrators which are buried in the medium, associated with a control system. Each vibrator comprises at least one inertia mass (), several plates () providing mechanical coupling with the medium, electromechanical transducers () connecting inertia masses () to plates (). A control system () applies to the various transducers () respective control signals so that the resulting elastic wavefield generated in the medium by the device is preferentially oriented in one or more directions.
