Abstract

Nonlinear transmission lines (NLTLs) are known to be a widely used generators of microwave pulses with operating frequencies from hundreds MHz to several GHz. NLTL's output power levels vary from KWs to sub GWs. Therefore, they appear to be a convenient tool for EMC testing. The lines that are able to produce sub GW output power levels are gyromagnetic NLTLs. These lines have some flaws in practical use, namely: low energy efficiency (about 10%) and high longitudinal dimension (more than one meter). Present paper discusses an experimental research for solving these problems by changing electrodynamic conditions in the line via changing of dielectric permittivity of the line by addition of ceramic beads.
