             abstract = "Nonlinear transmission lines (NLTLs) have been studied for 
                         high-power RF generation with good prospects of applications in 
                         pulse radars for remote sensing (SARs) and disruption of 
                         communications in the battlefield, for instance. In this paper, 
                         two 30-section hybrid NLTLs built using nonlinear inductors and 
                         capacitors (2.2- and 10-nF barium titanate ceramic capacitors with 
                         10-mu H ferrite bead inductors) will be described. For the test, 
                         the line is fed by a negative input pump pulse generated by a 1 kV 
                         discharge of a 0.75-mu F storage capacitor via a fast 50-ns 
                         switching system composed by an insulated gate bipolar transistor 
                         switch and its gate circuit driver. In the hybrid line tests, 
                         using 2.2-nF ceramic capacitors the maximum soliton generation 
                         packet obtained on the middle section had a frequency of the order 
                         of 33 MHz with voltage modulation depth (VMD) of around 700 V. For 
                         every single shot, approximately 10 RF cycles with small damping 
                         were noted. With the hybrid line using 10-nF ceramic capacitors 
                         the soliton generation obtained on the middle section reached a 
                         frequency of the order 10 MHz, and VMD of around 200 V. The main 
                         conclusion from this experiment is that hybrid lumped NLTLs may be 
                         used to achieve RF in megahertz range with higher VMD compared 
                         their counterparts (i.e., capacitive or inductive lines) because 
                         of their stronger nonlinearity with the use of both nonlinear 
                         elements.",
