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.
