Abstract: 

The results of investigation on synthesis of the layered composites "ferromagnetic-ferroelectric " for usage as an active dielectric of the impulse current and voltage generators' forming lines are presented. The structure of composites with simultaneous change of their effective permittivity and permeability to achieve almost constant wave impedance of the forming line at electromagnetic waves propagation are proposed. The technological methods, which provide obtaining the layered composites samples by cold pressing, are described.

Keywords: 
layered ferroelectric-ferromagnetic composites, non-linear electric and magnetic properties, cold pressing method, forming lines, pulse generators of currents and voltages.
