Output performance of ferroelectric-ferromagnetic multiferroic pulse forming line

Output performance of multiferroic pulse forming lines(PFLs) were investigated. The multiferroic PFLs were fabricated by utilizing (Ni, Zn) ferrite-BaTiO3 ceramics composites. Square output waveforms with different widths were acquired under the conditions of different magnetic circuit schemes. With “closed” magnetic circuit scheme formed by high permeability materials, the FWHM of the output waveform is 201 ns. Relative permittivity coefficient approaching 2 000 and relative permeability coefficient more than 1.4 are calculated respectively. The impact of multiferroic PFL’s topology on output characteristics is analysed based on the concept of effective permeability. As the parallel plate multiferroic PFL is concerned, effective permeability is determined not only by the permeability o
