摘要： The object of the invention is to provide a method and device for use in the field of intense electromagnetic pulse generation, for example for investigating or influencing materials structures as well as for use in EMC investigations, so as to provide a novel technological alternative for developing further areas of application. This object is achieved in that the structure of the core member of the device essentially takes the form of 2 + n (i.e. 5 when n = 3) electromagnetic resonant cavities fitted into one another according to the "Russian doll" principle; and in that the resonant circuit system is connected for circuitry and metrological purposes to the pulse generators (33, 34, 35, 36, 37), used for generation, and to an evaluation and control unit (38) and a vibration-measuring device (40). The invention concerns a method and device for generating electromagnetic pulses on the basis of electrical, magnetic and mechanical interactions between electromagnetically and mechanically oscillatory systems and can be used in fundamental research for materials structure, solid-state physics, material investigations and EMC investigations.

摘要： The invention belongs to the field of materials science, more specifically, to the technology for the production of microstructures - the development of elements of microelectromechanical systems (MEMS). This system comprises a magnetostrictive vibrator (1) consisting of multilayer ferromagnetic plates, the operating part of which is attached to the concentrator-sonotrode (2, 4). Between the end parts of the magnetostrictive vibrator (1) the gasket (3) is installed that insulates the temperature and the liquid. The entire magnetostrictive vibrator (1) is housed in a sealed housing (9) with the coolant (10) circulating therein. The magnetic conductor plates of magnetostrictive vibrator (1) are wound with windings (6) and (7) comprising terminals which, like the signal from the temperature and vibration sensor (11) on the mechanical vibration concentrator (2, 4), are connected to the excitation and control generator (8). The operating part of the concentrator-sonotrode (2, 4) performs the forming procedure by applying pressure to the polymeric material (5) on the tray (13). The comprehensive and timely effect of high-frequency vibration excitation and increased temperature and pressure on the formed polymeric structure allows to increase the efficiency of the whole process and the quality of the structural elements to be produced.
