Abstract :
The nonuniform nonlinear transmission line (NLTL) is presented. The NLTL is based on parallel-plate ferroelectric (FE) capacitors. Figure of merit defined as the relative change of the reciprocal steepness of the wave front at NLTL input and output is suggested to characterize the NLTL efficiency. Formulas allowing the calculation of figure of merit for nonuniform ferroelectric-based NLTL are derived. The designed NLTL demonstrates three times increasing of front steepness for input rectangular video pulse of 1.5 ns front duration and 40 V amplitude.
