Application of dielectric ceramics on solid-state pulse forming lines

The paper investigates the dielectric materials for compact pulse forming lines. According to the interrelation between parameters of pulse forming lines and dielectric properties of ceramic materials, the strategies of the material choice and assessment are presented for the solid-state pulse forming lines of dielectric materials. The microwave ceramics characteristic of adjustable dielectric constants are found to be relatively ideal candidates. The solid-state pulse forming line fabricated from the Ba-Nb-Ti microwave ceramics, can output pulses with a rise-time of 5-6 nm, a pulse length of 13 ns, and a flat top of 5-6 ns, and its breakdown strength is more than 17.5 kV/mm.
